Individual cylinder timing maps

As much as I have been on the dyno fiddling I never tried to zero out the timing retard that is present in the number 1 and 2 cylinders in high rpms (see picture of cylinder 1 vs 3). I also recently noticed that on some open source E85 maps those tables are all zero'd out. If high octane gas is used, can those be safely zero'd out or is there another reason for the retard in cylinders 1 and 2?
