What I do is far from perfect, but i'm refining it as i'm going along. Below is a link where you can see a typical file for 1 day's practice where I was able to plan in 100 minutes. I mainly use ideas from pebber's module 1 and 2, but you can also see exercises from other sources like modern method for guitar (MMG) and troy stetina's metal lead guitar (to the stage solo at the end of the file.)
Very first column the actual time accompllished, 2nd column amount of minutes planned, then the speed at which the exercise is to be done. Then obviously the description with optional notes in italics.
Originally this file is made in iwork pages, where I added a SUM function at the end of the first column. The function is now gone when I exported it to doc. But you get the point I guess.
