There is a threshold where the engines take a major factor to get to the next
depth in their analysis.  If I know that an engine can do an 11 ply search in N
minutes then I can set my time accordingly.  However, if I just limit the time
to say 3 minutes, the engine may only be capable of getting to ply 8 in that
time.  So I've wasted an analysis because the depth is too shallow.  I'm looking
for the threshold where getting to the next depth is just not worth the
exorbitant amount of time to get there.
