My initial numbers are up:

3 toons, 3 full days, 13 planets + 3 toons, 2 days, 12 planets = 50mil profit in P1 products.

Add in 3 more toons with 12 more planets, fill out the second toon cycle to the full 3 days, I believe a realistic estimate would be about 70 mil profit every 3 days.

Assume a 30 day average month that is an approximate 700 million month. 1 30 day Plex is about 330 mil (I believe, don't shoot me if im off by a few million) so PI alone should be able to fund 2 of my 3 accounts with some change leftover. And this is in no way optimized.
