This is the same for other programs. Hiarcs had a patch in Oct and
no new testing and separation of results was done. This also gets back
to a point I tried to make before testing of Tiger, that it was logical
to only test the released version.

It should also be noted that Junior 6a's rating 1st, includes games
from the weaker Junior 6. In the case of it's loss to Fritz 5.32
the majority of games were J6. I have not seen a breakdown yet it
is likely that the majority were prior to the upgrade.

If that be the case then they must also re-test. Junior 6a since as
stated above it's results include Junior 6's. Then maybe they should
also re-test Hiarcs 7.32 with it's book improvement of Oct and seperate
it's results based no the Oct patch.........where does it end?.
Also all those programs you named were sold as individual entities and
as such IMHO deserved separate listings.
Thanks.
