I don't think that they do implement pondering equally well.  But that is the
native mode the engine operates in.  And it is the mode the engine will be in
when playing serious games.  Which means that is the mode that will be used to
produce what I call important results.  So if you have a pondering bug, it will
show itself in the important games where you use pondering...

IE if you race an Indy car, and your motor won't survive at 13K RPM for a 3
hour race, who cares if it will survive at 10K rpm on a more curved track,
for only a two hour race.  When all the important races are at 13K for 3 hours.

The important testing comes from 'real-situation' testing...  Not by trying new
tires, different track, new fuel, different rear-end ratio, different
transmission ratios, different supercharger boost, etc.  All of those tests are
interesting to different people, but they don't say a thing about who gets the
checkered flag on race day...
