For the same shading scene, the electrical shading losses calculated using 'Module Layout' mode ( 3.9%) seem to be higher than losses calculated using 'Acc. to module strings' ( 2.8%) at 100% fractional effect. This seems physically impossible considering the 'Acc. to module strings' mode is supposed to represent worst case scenario. I tried testing this for two systems - tracker (without backtracking, ofcourse) and fixed tilt and both these cases exhibit this behavior. Would you know what might be causing this based on attached screen shots for the tracker system?

Perhaps you have used Half-cells modules ?
We have corrected a problem in the Module layout calculation for these particular modules in the version 6.76.
