Finally found something regarding my assumption;

"there is a maximum of 10 of each Dipster per island".

Given 7 Dipsters, that would mean a maximum of 70 Dipsters, drastically reducing the maximum amount of Coins that can be earned.

It would also put Rare Punkleton back on the map as being the best option.

Specifically, it works out as follows: 89 Rare Punkletons * 240cpm = 21,360cpm

1 Punkleton * 168cpm (75% happy) = 168cpm

70 Dipsters * 120cpm = 8,400cpm

total cpm = 29,928

total cpm/24 hours = 29,928 * (24*60) = 43,096,320

Still a very tidy sum :)
