any one know?

I am also curious.

It'd be nice if there was a breakdown of trainers and skill books + experience in each skill.

You can get a maximum of 80 perk points, since taking every Skill to 100 leaves at level 81. How many trees you can "fill" depends on which trees you choose, and whether you choose to perk and/or max every talent in those trees.

Leveling slows down a lot after 50, so most builds cap out around 50 perk points. You'll likely only invest heavily in 2-3 trees.

Also, you can get 80 perks if you hit lvl 81 which is the max level. There's 281 perks iirc.

on my one messing around file where i used the ognium infinium glitch i was able to get destruction, restoration, smithing, enchanting, block, and one handed all maxed out, with one half of heavy armor (so it wouldent encumber me) and i think three perks in speech. so I would say about 5-6 maxed depending which trees you use.
