No.  No published list.  Reasons unknown.

I'll start the ball rolling however:

Crafty version 19.20, running on an AMD quad 875 machine.  These are 2.2ghz
processors with dual-cores.  So it appears to be an 8 cpu machine.  Technically
it is a 4-node NUMA architecture where each node has two processors, each has
1024kb of L2 cache...  Typical search speeds are around 16.0 million nodes per
second.  Typical search depth hovers around 16 plies or so, +/- 1 depending on
the complexity of the position.  Far deeper in the endgame of course.

We have the 3-4-5 piece endgame tables.  I'm probably going to add a couple of
useful 6 piece files like krpkrp and kqpkqp...
