Reduce waiting time for users

[xehu]

I often get user complaints that they were waiting for too long; other users complain that the rounds move too quickly. This is mainly due to two issues:

1. Everyone has different reading speeds, making it difficult to advance the rounds at the same pace while pacing it appropriately for everyone.
2. Every survey is of the same length. So, because some surveys are longer than others, I set the timing to be a sort of 'lowest common denominator.' This means that the round pace is too fast in some areas and too slow in others.

I am wondering if there is any way to make the rounds less rigidly defined around the same timing and address some of these issues.
