A lot of uncertainty remains, clearly, from the size of the error bars.  But a
very impressive showing.  At any rate, ProDeo, Aristarch, and Ruffian are
probably the strongest free engines.  And since Ruffian has gone professional,
development of the free version has stopped (I assume).

In any case, Aristarch should certainly make us sit up straight -- if it had not
already done so.
