Hey guys! First of all, I should say that this only really bugged me when I started playing at the arcade after playing exclusively on 360 for a while. I had no idea that there might be a subtle timing difference so the worse my execution got at the arcade, the more I tried focusing and doing it just like at home. Now that I play almost equally on 360, PS3, and arcade I feel I can adapt and be more consistent no matter what I'm playing on. It's just nice to know that I might need to adapt. On PS3 and the arcade I definitely feel like I need to slow my inputs down a bit.
Also, I later found this post about GG which tells me this isn't unheard of.
As far as my test goes, I have a 360 TE stick that's dual modded with a Chimp. For this test I disconnected my 360 PCB from the Chimp and plugged it into the 360, and I connected the Chimp to the PS3. Both displays are DLP projection connected through HDMI. I don't really think the displays should matter here though since it's not really a question of display lag.
This is why I wanted to get a bit more scientific about this. Everything is hearsay, but everyone I've heard from has said the opposite (that the 360 runs fastest, and that the PS3 and arcade lag a bit so they're closer).
That's kind of it. For me, the big issue is that given the exact same inputs I get quite different results. I included those first few clips, even though I dropped the combos, because there was some weird things going on. In one of them, where I do the cross-up, Carl landed on different sides of the opponent on each console. In another clip, the alegretto canceled the j.2C on one console but not on the other.
