"do nothing" is too slow, need another key to hit to skip.

I would expect a final reaction time of under 100-200ms ideally?

Yes, I would also remove the automatic progression entirely. This should be driven by user input only.

Sorry, I meant I want to be able to do it faster. I don't want to be held up by an automatic progression.
