All else being equal, and in case you can really limit the CPU time and are not thinking about setting process priority only, I think the answer is yes: then ponder=on matches on a single processor computer would be fair too. I can still think of some possible technical issues, but then I can do the same when it is about ponder=off matches. Peter
