I don't miss a press, ever. I also didn't mess with switch timing, except for increasing it on one when it'd consistently double-press instead of single.
If you've set the timing too low, that'd be why they're being missed. Console games aren't going to register a 3ms press.
The thing that annoys me is my Azeron not being detected by Azeron Software on PC, so I can't check what my settings are to help with this thread.
