Finally.

Typing this on an iOS 9 device and I, as a human, cannot 'fast tap' enough for iOS to register a 'fast tap' and not delay. Try it here: http://output.jsbin.com/xiculayadu

It's a "slow tap" that eliminates the delay. Tap and hold your finger down for a moment. The delay registered with a "slow tap" is about 10 ms for me.

God that's completely unintuitive.
