If looked at in a different way, there are only four different platinum drop amounts from daily chance. One of the largest platinum drops is what an aquarium tank owner earns when someone gets a score of 35. The first five players also give a bonus of about 1%. What I did is divide all the daily chance platinum drops by this amount a tank owner earns excluding the first five player bonus. I've found that the four possible drops are 4.0, 20.3, 39.7 and 60.1% of what a tank owner earns.
What's interesting is so many platinum drops go up and down in proportion to each other. I have lots of percentages in
this thread. I'm trying to figure out posting, forum voting and pink link right now. Pink link is the hardest because there are so many possibilities.
All the data collected was when my account was below the platinum cap. If you earn platinum while capped, things get complicated. You can either earn a percentage of what you would've earned if not capped or just 1p.
