It's taken me over a decade to realize how significant a problem this is, but comparing GPAs between students with significantly divergent course history is idiotic.
At least in programs with a lot of course choice, a GPA largely measures a student's ability to pick courses in which they will achieve high marks, and punishes students who challenge themselves.
While I’m on about nice software, the @Iconfactory’s just-right iPad/iOS sketching app Linea was updated today. I like it. https://blog.iconfactory.com/2023/01/announcing-linea-sketch-4-2/
