I thought that the rule was that you needed 8 hours of not-doing-anything. Like, you need 8 hours to pull magic into your brain. I suppose if you could self-accelerate time, you could acquire 8 hours without 8 hours actually passing (Persisted Time Stop with Incantatrix, mebbe). Like, with elves and elan, who trance for 4 hours, sure, they're no longer tired, but they still need to sit and gather energy.

Arcane magic is kind of like drivers ed. It doesn't matter what loophole you find to get equivalent knowledge, you still need to fulfill the hourly component. Otherwise, no fly and no drive.
