Why does it matter the exact manner is - the end result is the same ?
The exact answer as it was already pointed out is that only when not attacking, she regenerates in 0.5 second tics for 4/6/8, which amounts to 8/12/16 per second total. Poison maps, on the other hand, always deplete HP, again in 0.5s tics but they vary in the damage they deal. I've been told Monday dailies for example deal 5 damage per tic, but Golden Armor X, which we don't have yet, deals 20 damage per tic.
What this means is that Rikka regenerates in similar intervals, but the mechanics are not exactly the same as toxic maps - she does not heal all the time.
Hope this answers your question.
