When calculating specificity in the shapeworks studio how many random shape samples are generated across the modes of variation to compare with training shapes. Is it a default value, based on the number of training shapes or until the mean value platau’s?

Hope this makes sense

It looks like the specificity computation is currently hard-coded to 1000 samples:
