I wrote this a month ago in the discord, but I've reworked it a bit and wanted to add a few things. If you've read it there already, I'd appreciate the reread 
So I'd want to start off with the fact that from the very beginning of me starting to play back in 2015, I've been firmly against 50hz being pitted against 60hz. A lot of things have happened in the community and on the leaderboards since then, but my view on 50hz has remained very similar.
Ever since the early days, there's been a decent consensus on that 50hz is advantageous. The easiest way to judge whether or not it is would be to look at the Mario Kart 64 leaderboards -- Where PAL did not have a choice to play 50hz or 60hz and see what dominates the top level rankings. I'll bring this up a bit later as well.
**Why Now?**I feel like this is probably an even more important point, so let me explain1. It's only been since may 2019 that all records have been done with 60hz, and now, it is again slipping away. So for the first time since the game's release, in 2019, you could say 60hz was viable to pick. This meant that all WRs can definitely be beaten on whatever region you're from, and 50hz would not have the stronghold on the game as it had done before 2019. And even then -- It's not like 50hz wasn't better at the time, there just weren't any players who would take up the job of playing it.
2. Some of the questions people have had about 50hz and 60hz have only gotten answered recently. I've heard the argument that maybe 60hz can get faster MTs than in 50hz, but we can see from TAS gameplay that the fastest MTs are still way faster than what 60hzers achieve nowadays. Then as we can see from mattilde's gameplay, clearly 50hz can compete with 60hz and outperform it, so it's not like the old wave of 50hz players were pushing the definitive limit of 50hz.
3. On top of that, a lot of players who were active during the first boom of MKDD (Richard, Andreas, Bunde) and people who followed their 50hz steps are now not playing anymore, and especially not because they *had* to because of technological reasons or competitive reasons. The only reason to pick 50hz now is that you prefer playing the game that way or that you want a competitive advantage.
4. And lastly, this change should've never have been a potential change -- I think combined should've always been a 'novelty' leaderboard, something to look at that's fun statwise, but not the main way of describing records, rankings, and overall performance.
**50hz vs 60hz**I think there's a lot of reasons to solidify 60hz as the only way to compete against everyone. Here are my most important points:1. Level playing fieldWe have the ability to let everyone compete fairly against each other, no matter their region and if they're on a non-modded gamecube or wii. It will also enforce a "tournament" standard that often already is in place (see: speedrun.com | TT1Try Tournaments).
2. 50hz's massive advantagesNot only can you have 120 seconds of input for a 60hz'ers 100 seconds, to me the reaction time and calmness of the gameplay plays a massive role. You have a lot more time to think about your adjustments, calm yourself down during slower parts, and even make more calculated precise movements to optimize MT speed for example. I can't help but describe it as massive as it really is at high level.
3. It's not necessary anymore.I mentioned this earlier, but in order to compete with people way back in 2003 and 2004, if 50hz would've been banned from the beginning, it would've required having a 60hz TV for PAL regions. Now these were already quite common and I don't think it was much of a problem anymore quite soon after that. Regardless, nowadays this is definitely not the case anymore.
4. The futureAn interesting thing to think about is that let's say 50hz remains active on the combined leaderboards, then starts dominating the top 10. Continue this cycle and you'll have a leaderboard extremely similar to MK64.
In MK64, NTSC times barely get any recognition even though it is objectively more difficult to drive as such. The only times there'll be some recognition is if it's an NTSC WR -- But even that a lot of people don't care for.
This plays into the fact that mkwrs.com is also fully combined (for both mk64 and mkdd), and thus, 60hz players will have to compete directly with 50hz to drive 'recognized world records'.
5. Indisputable advantagesAs a pro player myself, I know a lot of spots where 50hz could gain me a considerable advantage. For reaction time here are some examples:
- Reacting to DKM's shortcut hop over the grass
- Balancing on the DKM bridge
- Micro-managing lines
- Slamming into the fence 2nd hairpin in RR
- Optimally reacting to any waluigi bump pretty much
What it comes down to: A lot of 'pseudo-RNG' that is manageable by reaction rather than muscle memory, and fine line adjustment. To say 50hz' advantage is not that big wouldnt be true.
6. My own experienceHere's the thing. I have no problem competing against people, as such is the nature of a leaderboard. I don't care if they'd be better, but the problem is that to me, competing against 50hz has never been fun. Be it when I was climbing up the rankings, or the defending I do now.
For the people saying I should just switch if I think 50hz is so much better: Having played a bit of 50hz as an experiment, I personally felt like I was cheating. I had so much more time to react. But on top of that, to me, that's not how the game was ever intended to be made. JP doesn't have 50hz. NTSC doesn't have 50hz. It was a necessity. 60hz is the way the game was intended to be played, and it's what I enjoy playing most as well. That's what I like competing with.
**So what to do?**I think that preserving history is extremely important, and I also don't want to hurt people playing 50hz. HOWEVER -- it is also hurting people who play 60hz to have to compete with 50hz, which, in active and total players, is now bigger than the 50hz-group.
There's multiple solutions to this.
I've thought about this a lot but I think the easiest and probably best way would be to keep the combined leaderboards, but dial its importance back and turn it into a novelty stat page. This way people can still see how they fair against each other, but can still care about a 50/60hz record feeling as a proper legitimate record.
50hz Players can still compete for 50hz records, and in fact, people would be looking forward to 50hz records and seeing what the game can be pushed to. They'd have a lot more worth, and so would 60hz records. On top of that, switching between 50hz and 60hz would also make more sense, as you'd have different rankings to compete in.

@ndrew wrote on 01/15/22 at 17:18:32:also I just want to add I dont think your point about being able to do faster mts and better r techs is entirely correct. if you look at my early videos when I was competing with the top 50z players my mts are much faster and my r tech is on par. I think it may give an advantage in timing and reaction but 50hz players cannot do faster MTS and better r techs just be cause its slower, the timing is just different. Also i like combined ranks because its fun to beat the top 50hz times as a 60hzer
Because the game is slowed down, doing Faster MTs is easier than doing them on 60hz, which I think the main problem is about MTs in 50hz. Also, a lot of older 50hz players didn't ever bother trying to up MT speed to the max -- Even in MK64 this was the case until Xander G. came in and showed they can still be done faster on PAL (and NTSC)
On top of that, keeping the combined leaderboard as a novelty thing would still allow you to compare for fun without for example feeling demotivated by having to compete with 50hz
