This is a great idea, I'd love to see this working and am willing to help.

In a way we could describe this as storing raw AP gained.

For peer review, one issue I could think of:
Two Espers can teach the same spell, this means computing all espers to realize a single spell learning status%
Another solution to this problem is to ignore it, so if you already learnt 10% of a cure from an Old Esper you will start at 0% for cure on the Newly equipped Esper.
This will be an issue to consider for the Menu Magic list aswell unless you would skip showing learning progress in that list.

Another similar cool system could store AP and allowing the characters to spend it to learn stuff. That kind of system could easily be derived if the one above is implemented.

Yeah, I have been throwing those ideas around... My plan is to just remove partially learned magic from the magic menu, i don't need it trying to calculate EVERYTHING over and over... but it SHOULD be doable on the espers menu, since theres just a couple spells per esper, and you don't need to scroll around, it can be thrown up and be done... much more manageable. We could simplify things further by making it only for that specific esper, but I'd like to try having it check other espers first.

And for choosing to learn with AP... I like the idea, but its too far removed from the learning system for my taste... and would also require some custom menu building for selection and such. But it would be great for a job-class system, which this patch would also help a lot with.

The first thing i need is all of the locations in the ROM that magic is observed/used/learned. Pick a bank, and find some addresses so we can plan our code!

Thanks!
