Whats the best time interval to get money from girls?

[ronpotter695]

I have 68 maxed out affection girls, 22 of which are 5* girls. And 36 other girls but they aren't maxed out so their monetary contribution is less than $10,000.

When all the girls are ready to get their money collected its around $680,000.

If I take the average $/hr for the 5* girls and add the 3* girls they would be =$139,200/hr    ===>  $ 3,340,800  for a day.

Which is quite a lot, I could upgrade epic level girls daily if I use it with money from villains and champions but getting this amount of money is impossible unless you click on every girl after the money gets filled.

So I'm asking whats the best time to log in to collect money? 

Also some 3* girls hold a lot of money.

My guess is every 2 hours
