Jackie,
please note that (at least imho) the desire to obtain "better" R-factors
does not justify excluding data from analysis. Weak reflections that
you suggest should be rejected contain information, and excluding them
will indeed artificially lower the R-factors while reducing the accuracy
of your model.
Cheers,
Ed.
