For deep analysis, I'm sure people like to wait longer than 2 minutes, when they
can see its opinion changing every few seconds.
Only, if they want a spot check or spot opinion, many times one after another,
then they would like to see something intelligent within about one minute.
So you are saying that without blitz maximization, it would get a better
evaluation in one minute, than if it were maximized for blitz?
