This is kind of off-topic, but the cost/benefit of RP-XP is greatly dependent on how AFK the player is. The less he's paying attention, the less of his own time he's spending on the game. So the cost/benefit of RP XP can range from relatively insignificant to exceeding many DM sessions. As with all other un-throttled gains in ALFA, the more you exploit it the more you get out of it, though unlike other gains it is fixed relative to real-time.
My last PC had something like 10% of overall XP from RP. I'd just log off and go DM if there was no adventure to be had, and back then my computer wasn't powerful enough to write code and stay logged in at the same time. So I'd expect this would be a common number to see from a PC who engages in little social RP.
Proposal for Xp awards for Bios, please give your thoughts
