So TF-5 (alkaline), in theory requires less wash time than Rapid Fixer (acidic)? And it fixes fiber prints in a minute but needs 10 minutes to fix film? And overfixing prints is bad because it takes longer to then wash the print?

I appreciate all the chemistry knowledge available here, but I'm getting a little lost in it. Very willing to learn but please speak to me as though I'm a drunken third grader with a less than rudimentary understanding of the the universe.
