They are not commensurate at all.

Hiarcs is a slow searcher and Junior is a fast searcher.  Both programs use very
different nomenclature for what they call a "ply."

Apples and oranges.  You can't count the nodes and tell how good a program is
except against itself.  You can't count plies either, unless they mean exactly
the same thing and they never do.  But I think even so plies is a better
indicator of strength than nodes.

Look at Diep, CS-Tal, M-Chess, Hiarcs and some of the other "low-nodecount"
notions.  If you tried to extrapolate their strength from their nodecounts you
would think they would run screaming from TSCP.
