Hi! What do You think about invprofcheck result while profiling? My own experience tells me that in general case the invprofcheck errors must be the same size as profcheck errors. If the invprofcheck errors are larger than profcheck errors, the profile is likely overfitted and colprof -r value must be icreased. And vice versa. The equivalence of inv- and profcheck results asserts that profile fitting are well-balanced and both B2A and A2B tables are quite exact.
