i have diffraction of a crystal showing Rmerge 50 % resolution 21- 3.5 A. this is due to crystal decay with time while data collection . multiplicilty is 11 .0 and data is 99.6 % complete . i want to know that is this a good data to solve structure with MR . i got solution with this data but the R factor is 46.5 and R free is 51.4 .

i want to know that if R merge is too high we should proceed to solve structure or not .
