Yes. The comparison is completely senseless no matter how you look at
it, but you're preaching to the choir here :)

I initially tried to test against Deep Sjeng 1.5, but it limits the
search hard to the depth that is set with 'fixed ply', whereas
Shredder & Crafty still allow extensions/quiescent search.
Obviously, this gives entirely different results than when I relax
this restriction. And we're still at the same ply depth in the
same program :)
