Procheck puts out such a correlation (% most favorable
vs resolution) in the _04.ps file. For example look at
page 7, first panel of the sample procheck output at:
http://sb20.lbl.gov/SQR/procheck-2H88.pdf
It appears that 83.5% would be well above average
for a 3 A structure according to procheck statistics.
(However I think most structures nowadays are
"above average" by procheck statistics)
