The statue of Sami in the door I think was enough to convince me that he was a serious karter at least.

Okay, so I guess it can't hurt to give criticism of what I saw in person.
Pros:
+ He performed high quality times on stream at request, including times like a 4"23 KB1 lap and getting a time .09 off the WR of BC1 lap. He proved capable by getting 47"06 on the first try on SGB, and he even pulled off 2 high quality laps on SG that, if he had finished lap three, he would have beaten his PR by a large margin. He also got under .3 away from his PR on BL within the third or fourth attempt.
+ His DS is different than other systems I have played on, but that's because it is so beat up. The D-Pad is so screwed it's unbelievable. But this actually seemed to give an ever-so-slight advantage to him, because he just had to move his fingers and not really press down at all. It was worn down that much.
+ Changing cartridges did not effect game play, and the game he's playing on seems fine.
+ Fenner's responses to requests was quick and willing. While on stream, there was absolutely 0 possibility of cheating.
+ The timescroll matched what is on his profile. A couple faster SC times, but they were not submitted or were fixed.
+ He has an iron board and plays on the floor
Cons:
- Long cheating history, even recently after he told me he was done for good. Unpredictable at this time, so he will need to reinforce himself with frequent live streams or he should be frozen.
- Had replies like "almost never cheating" then when pressured said no more firmly. This could be a factor of nervousness due to public speaking and being questioned on a more personal topic, but this cannot be assumed to be the case.
- He has Dolphin on his computer, then mentioned something about forgetting to delete it.
- I never got my freeze pop.

So, to sum up, this meeting helped Fenner more than hurt him I think. I'm confident it showed that he is both a great player and a decent ironing board. However, he most certainly needs to find time to stream whenever possible, and he needs to continue making videos for each PR. This meeting was a lifeline tossed out to the water to save him from drowning, but he's not coming back into the boat and the rope holding him afloat could be cut at any time.
