The Column is already multiplied by 100 to make it a percent. So if I try to make it a percent format I have to first divide by 100. I think it would make more sense and be more intuitive if it wasn't multiplied by 100 but just formatted to be a percentage. That way the percent sign is there and it seems more intuitituve to me. This is probably a thing that goes deeper than summary, and this may cause problems.
