Indeed ... or SHARP ;-)

I must say I stopped looking at R-Cullis/R-Kraut values a long time
ago (maybe I still should), but found phasing power immensely useful -
much more than FOM.

Of course, if you used program A to get those SIRAS phases at the time
you should only report statistics as given by that program. Maybe
Phenix has those stats "somewhere": asking the phenixBB? I would be
surprised if it doesn't compute phasing power, but maybe it doesn't.

If the stats aren't there then this is just what it is. Re-running a
different program B to get statistics is rather confusing: the
resulting phases could be worse (and stats misleadingly poor) ... or
of course could be much better. But then: some better phasing might
give you nice stats for reporting - but it wasn't what actually
happened at the time. It might be ok to convince a referee, but should
probably not be put into a deposition/paper.

Yes :-)
