I think 55 percent from center is the theoretical limit. This looks about right.
55% is 5/8". I can't hit that far from center regularly. ~9/16" (50%) is my best.
I believe it. I probably just can't hit 55% as reliably as I can 50%. Another possibility is that I use the OB stripe (Aramith, placed vertically) to "measure" - any chance that's wider than 1 1/8"?55% is the largest I measured in the past.
