It turns out that I was able to get all 52 girls currently available up to Lv100K. With a combined Harem level of 5.2M, Spiral power has reached 30Q. However, it's taken me over a week to get everyone up to that point, even with an Auto-Clicker. However, before the update applies itself, it's just above 4B. The amount of work involved is enormous. My Click Power right now is probably somewhere in the 100-200QT range, considering it cycles through -21.47QT to 21.47QT in increments of T several times.
I'm currently at Countryside Lv8400, and I have 117586 Pearls waiting to be redeemed, plus the 52K from my Harem. The Spiral seems to be working at full power, so the recent update has fixed the problem. Haven't tested it in the Campus or City, though.
