Lots of mistakes and misunderstandings everywhere!
I didn't specify it on pinside, but as I mentioned here, WPC flippers get serviced every 4ms as stated in Josh's quote. I completely agree with him that there should be an AVERAGE delay of 2-3ms for WPC games in terms of flipper response, just like I think there should probably be 1-2, maybe more, for our games.
Something is definitely wrong with all the timings thrown around because like I said, no one complains about the 2.5ms AVERAGE, INCONSISTENT delay on WPC. I'm expecting them to find that the delay is much much worse on remakes based on the OPs measurements.
I haven't seen Pinball 101 and their timings and the 8ms difference that was mentioned, but that seems hard to believe to me that it's that quick. But I don't have any reason to actively disbelieve them, either.
