Your first point is not a full point. That is only brought up as an side effect. It isn't the primary objective of the change.
Your second point has varying degrees of impact. More than a minute is too long for that kind of decision. Factoring this in, in a best of 7, played out fully, you get a 27 minute set, plus a minute for anything before the first match. Realistically, playing out 14 stock should not take you anywhere close to the full 21 minutes, so it is not the average time spent, but rather an extreme scenario.
Pools sets should likely be less than best of 7.
@Niko: Use examples, not hypotheticals.
