i forgot a few factors
daily errands give 60 poly a day *20 = 1,200
SD resets once every 14 days, so you will get to do at least 1, that's 720 poly if you get all Ss. new total = 1,920
DA resets every 14 days, at 6 stars that's another 300 poly. new total = 2,220
the daily website checkin gives 60 poly over 31 days. so you can expect to get 40 of those.
the newstand / ashoo pays out 5 times in 30 days. let's say you get 3 of those at the lowest possible payout of 20 poly. new total = 2,320/160 = 14.5 rolls
so you need to enter the VH banner with around 120 rolls to guarantee getting it
(i forget if yamcha gives any resetting poly, but i don't think it does)
