    That suggests the problem is lack of fit. When I look at the histogram, I'd bet that your actual distribution has a bit heavier upper tail than either a lognormal or a gamma distribution can offer. Actually, I am taking the gamma inverse in the next step to correct one series w.r.t to the gamma parameters of another, hence I have to take the whole series in the calculation.
