Because it _assumes_ it will save time here and there by "pondering" correctly
and it adjusts the time target for each move based on this assumption.  But
the assumption is _wrong_ since it isn't pondering at all.  The time allocation
for ponder=off simply needs more tuning.  But I don't _ever_ play serious games
with ponder=off so I never test or tune for that...
