The maths behind crossover says it is not an issue, with a 1mm off set scope and a 35y zero you should only be about half a mm off at 15 and 55y, I would challenge anyone who says they could show that on a target!
I think the problem of an off set scope is more to do with the shooters eye view. Your scope will have a small exit pupil requiring an eye alignment tolerance of less than +/- .5mm, so when you are behind the scope positioning your eye for a shot the action and scope can be plainly seen as not being in line which messes with your head and eye scope alignment, well it does with me anyway. The crossover is not an issue but the perceived misalignment is.
HFT, for people with only 2 buttucks!
