The point is it was a similiar experiment.  The experiment was to see the
difference between having TB and not having TB using the same program as a
reference.  Also as I mentioned, I only had a few TB's and their effect was
minimal.  That is why the score was almost identical.  Again, I say that playing
a program against itself, it is reasonable to expect it to play very even.  That
being the case then any changes such as PB/NoPB should account for the
difference in score.  Same with TB/NoTB.  This is a pretty simple concept.
