To skip the introduction, scroll ahead to the picture of a post by Master Kek.Sorry to have taken this long to respond, but I have my reasoning for it:
I dislike bringing up my adult problems where kids are at. But for the sake of clarity, I will inform that I have been dealing with depression for about two years now, and losing a new world record due to a cartridge/system failure has been a large fuel for my depression. And when I'm really depressed like this, I want to be left alone for a while.
On my usual days, despite my depression, I am very motivated to play Rainbow Road, it's my favourite part of the day and very good for winding down after working for 9 hours as programmer. My recent, heavier state of depression has led my daily routine to a habit of taking my sleep medications as soon as I arrive home from work, then working on some Xenoblade for an hour or two, (more about this in a later paragraph) simply waiting for the sleep medication to go into effect and knock me out, just to get the current day over with.
I am currently not touching my 3DS in my daily routine, I am simply too depressed to open it and play it. I need to send it to Nintendo to have them repair it anyway, since the slidepad and c-nub are actually acting really weird… Currently I just don't feel the motivation to mail Nintendo about it, since the warranty just ran out two weeks ago, I might as well buy a brand new one next month knowing Nintendo's policies.
Work as a programmer, and work at home (again, more in a later paragraph) is actually a really good distraction from the thoughts that make me feel bad, but it's not a cure. Unfortunately, not even some of the heaviest anti-depressants helped over the last two years.
What have I been doing instead of playing Rainbow Road my two/three free hours of every week day and on the weekends?On the weekends, I have been working on my Pokémon Stadium Let's Play video's for YouTube, I know that only about five people actually watch each episode, but as I have stated before, I want to use my YouTube channel as a showcase of my video production skills, if someone ever wants to hire me as video editor/producer again, since it has happened once, it will probably happen again some day.
On the week days, after work, I have been helping out the guys over at the Xenoblade Chronicles X (fandom) Wikia. It is my favourite game on the Wii U, and I am hoping to one day do a 100% Let's Play of it, in the same way as Chuggaaconroy did one for the original Xenoblade Chronicles. But before it is time to Let's Play the game, what better way to research the game that you love, and to learn all the in-and-outs than working on the website where most people get all their in-depth information about the game from.
Xenoblade Chronicles 2 is coming out soon and the coverage of Xenoblade Chronicles X on the Xenoblade Wikia is still very far from complete and comprehensive, that's why I am helping them.
You may have noticed on Miiverse, that I have done posts like these, as you can probably tell from the previous paragraph, I make these posts to help the Xenoblade Chronicles X Wikia, not for anybody's entertainment. The Xenoblade Chronicles X Wikia is still lacking all of this mapping of all the segments their goals, that's why I have taken it on me to do it myself.
https://miiverse.nintendo.net/posts/AYMHAAADAAADV44iygQ3jQhttps://miiverse.nintendo.net/posts/AYMHAAADAAADV44bKXZDQQWhat made me motivated to do this response to the criticism is Martijn commenting on one of those Miiverse posts, things like "Go work on your Rainbow Road problem." or "No one is interested…".

Again, these posts are not for the Mario Kart players their entertainment, they are to help the Xenoblade Chronicles X Wikia. Please don't talk to people in such a seemingly demeaning way.
Now, with that out of the way, I will respond to some of the criticism I got when posting about my 1:36.159: 
If you have followed my Twitter for a long time, you know, that around the April fools time, (if I can think of a good one in time,) I always pull a little April fools joke every year, this video you pointed to happens to be an attempt at one as well.
But the keen eyed among you will notice that it was uploaded 22 days late, the thing with the March/April period this year is that I was busy with my graduation internship my Bachelor's degree, on top of being deadset on getting a new Rainbow Road World Record before the 1000-day mark of my first world record, on top of wanting to finish the first half of my Pokémon Stadium Let's Play before my graduation date. I simply didn't have time in March to sit down and think of a good April fools joke to pull off this year.
I always sprankle little hints to my jokes being fake, for this one, I made up a story extra rediculous to the point that it was unbelievable, on top of that, I claimed to have already unlocked the Golden Glider, which is impossible.
This year, instead of keeping it to Twitter, I took my joke to YouTube, and it blew up in my face overnight, I was extremely overwhelmed by the viewership, it got a hundred times the amount of views and way more comments than I expected it would get. I did delete some comments while I was overwhelmed, not knowing what do to from there, hoping to restore them one week later, which I discovered is not possible on YouTube, unless you contact YouTube themselves to do it.
If I had noticed someone putting this joke time on mkwrs.com/mk8dx, I would have
immidiately contacted the person to inform them that it was a joke.
To close this one out, I've made joke video's, where I lead the viewer on before, outside of the April fools period, like this one:

Hey Martijn, I wanted to contact you on your YouTube video about the time, to see if we could work things out, but you had comments disabled if memory serves correctly…
For the last three and a half years, I have not cared about any other track than Rainbow Road, I want to focus on getting a time as good as possible on just that track, because I love playing on it.
I only play Rainbow Road, the only exception is when I see a new world record with a new strat or one that is really optimized and I think to myself "Hey, that's pretty cool", I try the track for an hour or two, to then go back to Rainbow Road.
When I saw a thread about No Mushroom Time Trials, I got a little interested and thought "While I don't care about this in the long run, it looks fun, so let me try this once for a few of the least-played tracks". Maka Wuhu was of course one of the tracks that I did one attempt one, but I didn't immidiately report the time of that first attempt.
If you follow me on Twitter, you know that I make a bunch of typo's when Tweeting, I don't correct my typo's in a follow up Tweet or anything, because I simply don't care enough to scan what I typed for typo's.
Only Martijn and Frederiek will be able to read this, so you can ask them for a confirmation on this, but even on LinkedIn, which is a website where you're meant to show your most professional side, even there do I make typo's and look really dumb. Here is an example of some freshman student that needed to interview a few people that graduated from the Bachelor's degree that he just started, my response was really unprofessional looking, the problem was that I didn't care enough about this person to doublecheck my response to him for typo's.

I don't remember what time I reported on Maka Wuhu, what the actual time I set was and where I reported it, it was simply a too long time ago. However, what I am fairly certain about, is that whatever the time was that I reported, it was very likely containing a typo, because I didn't care to enough about No Mushroom Time Trials to doublecheck what I typed for errors.
To close this one, this one is indeed where I ****ed up out of neglegence.

If a time without picture/video's/splits does not count as World Record, then what about these records, from the same track? Should these be deleted?

That was the criticism that I really wanted to respond to for a while, because the comments didn't portay the whole picture.
What is the best course of action in my opinion?There are a few options in MY opinion.
1. List 1:36.159 on mkwrs.com just like Nyko and Doco's times:If you list Nyko and Doco's times as World Record, while there is as much information about those four times as my 1:36.159, (in the case of 1:38.483, even LESS information) then I personally think it is only fair to also list 1:36.159.
2. List 1:36.159 on mkwrs.com until it has been beaten:This second option stems from the same opinion as the first one and branches from it, but the difference is that 1:36.159 will get deleted once it has been beaten, making it not clutter the World Record history of Rainbow Road even more.
3. Keep 1:36.159 as the "pending" World Record until it is beaten as Kleenex does on the European Top 10 Thread:Just like how it was done with Kubica's time, I think it is fair to keep 1:36.159 as pending World Record until it has been beaten, then you can decide between option 1 and 2 what happens from there.
I don't think 1:36.159 should be avoided to be listed like it's the plague, it is the fastest time to ever be performed on Rainbow Road, and also the highest skill level to have ever been performed on the track, knowing how far I was in front of my Ghost before the final SC.
If anyone has more criticism, feel free to post it in a response, I will try to answer it when I have some free time.
For the next few weeks, I will be helping out on the Xenoblade Chronicles X Wikia, while completing the final 10% of the game that I have left to do. After that, I WILL come back to beat 1:36.159, the day after Miiverse ends, I just needed this break from the game right now.
Edit 08/10/2017 13:19: Corrected some typo's.
