Are you not tray developing under a safelight? You would be able to see it developing and not stop at 2:40 if it wasn't long enough.

Otherwise, did you expose the wrong side of the paper? ....It's happened to me more than I would care to admit.
I'm not tray developing because I don't have a permanent darkroom at the moment. if at 17 degrees 5 1/5 is enough then at 20 degrees it should be around 3 minutes right? give or take.

so I'll try more developing time.

Another problem I have is that I can only shoot one, process one, shoot one - process, so it all takes a long time. anyway, nevermind.
