Hi Bosco, You have the right formula. The issue is that some of the reported numbers may be rounded up or down, so that entries with weights of 0.49999 and 0.50001 will be recorded as 0.50 in the protXML file. The num_unique_peptides should match the ones that have is_contributing_evidence set to "Y".
Do let us know if you notice any discrepancies, preferably with an example.
