Mic, "To what degree do you "cant" your bow?"
You can really see my natural cant in my avatar picture. But regardless, whatever cant the shot requires, my reference spot will still be on basically the foot of the animal in the picture.
If what you show works for you , do not change. But! "Cant" or not, if you are holding that much offset, I SUGGEST that there is an alignment/form problem. I cannot say more with out seeing you shoot as Rob suggests.
