I do not see the point of testing a Deep version and a single version of a
program on a single processor.
IMO this is just a waste of time.
You could have tested a strong amateur engine instead.
Aristarch,List,Little Goliath or CLC for example.

No wonder

Junior 8 did not play against Shredder 7.04 nor Shredder 7.
It did not play against a Chesstiger version too.

Instead it played 60 games against Shredder 5/5.32, 52 games agsinst the old
Fritz 5.32 on inferior hardware and 62 games against the old Nimzo 7.32
on inferior hardware.
