I tested concentrate in the lowest and highest mana rooms I could find: flickering (town green NW) and brilliant (east of Silvyrfrost).
I tested evoke in 4 rooms: the one in Crossing, the one in S'lai, the one in Haven and the one in Nimbuses. (Skipped the one in Leth, 'cause I'm not sure where it is.)
Concentrate data:
Room | % of a rank gained |
Flickering | 0.10% |
Brilliant | 0.17% |
3 second roundtime, 1 minute timer (per room).
Evoke data:
Room | % of a rank gained |
Crossing | 0.02% |
S'lai | 0.02% |
Haven | 0.02% |
Nimbuses | 0.03% |
2 second roundtime, 10 minute timer (per room).
Conclusion: Concentrate gives roughly 6 times as much experience as evoke, meaning locking PP by "evoke walking" would require 6 times as many rooms. Locking Bardic Lore that way would require even more, since it's in my primary skillset (and I have 150 extra ranks of it). So I would not use this as a training method. Because of the long timer, "evoke sitting" (sitting on a room while I do other things and evoking every 10 minutes) would only provide a negligible amount of exp.
