I think that I’d have to follow suit that it all depends on the construction of the PCB itself. As long as it’s acceptable, anybody can get used to the amount of “lag”. Any player on converter set-ups knows that there is just a bit of lag that naturally happens, but they’re usually adjusted to it. You can be a great player on a TE PCB, but then get an HRAP3SA PCB, and things are off? Doesn’t make you a bad player. Just something has been changed. Much like preference of Sanwa or Seimitsu. Sure, maybe a “less laggy” PCB makes it “better,” but there’s a lot of quantifiers of better. Is it common ground? That’s a big deal. How expensive was the PCB to make? Doesn’t matter for one frame of lag if you can make it at half the cost.
Yes, there are always discrepancies from stick to stick. That’s why you don’t play on a different stick every time. You hopefully practice on one stick, bring it to tourneys, and play on it. That’s why you mod it so it’s perfect for you. That’s why you make a custom, so it is perfect for you.
Honestly, I didn’t bother to see how much lag they quoted, because nobody has ever complained about the TE being laggy. Once you adjust to a certain amount of lag, 1 frame less lag means 1 frame of lag different than what you’re used to, which is not necessarily a good thing.
