I do.  I display the time when the PV changes.  that is all I need to
compute the speedup.  Node counts are not needed.  I don't care about
the ratio of nodes on 1 cpu to nodes on 4 cpus.  I care about the ratio
of the _times_..  Last time I played a game of chess, my clock ticked off
seconds, _not_ "nodes"..

that is all I see reported here when people are comparing programs.  Because
it is _the_ performance measure of interest.  Nodes scales perfectly with
time/speedup.  If you know one, you can derive the other, because one is a
direct function of the other.
