Time breakdowns?

[JonnyWhoopes]

How do you properly determine your time breakdowns? I suppose you could do averages of each step, but I feel that lookahead is inaccurate... is there any other way to do it, or is that how people normally do it?

Using this is very nice. It barely affects your time at all if you just snake your hand to the spacebar and back.
