We could learn to embrace the R-factor on intensity that small
molecule crystallographers are comfortable with but, as you say,
people are not used to these.
Small molecule crystallographers *still* prefer to talk about R-
values calculate on F (with an N-sigma cut-off for weak reflections -
I forget what N is "by default"), getting on for 30 years after
(mostly GMS) programs started default refinements against I.
They do talk about Rs against I, but feel better when they have a "2%
structure" rather than a "14% structure", even though the model (and
experimental details) are identical.
So I don't think this is a show-stopper.
