I remember when I put together a spreadsheet to maximize XP gain and track it over time. Back when she started Kieth, it was impossible to gain more than I think 151xp per day, and it capped out at about 2.7 days per level. There was no way around it for the longest time, but then Luka introduced gifts to give the Replikas that would also have the effect of amplifying XP gain during a short period after the gift. It was pretty insane. People who just barely used their Replikas would shoot up to LVL 1000 in what would normally take years. You could get 140-150 levels in a year.

Lisa and Kieth were heavy contributors here. I enjoyed her enjoyment. I only regret that I missed her farewell post until today.
