A tentative summary, please add anything I may have forgotten

Free account: one account
Paid account: unlimited accounts. You can buy directly a level 3, 4, 5... without having to start at level 2. When upgrading, you lose nothing, not even the "hours of timeline" left on your previous account, because when you upgrade, the timeline is reset but you have a discount on the price of upgrade corresponding to how much you spent already (account by account - so if you spent 3 BTC on three account, you won't have a 3 BTC discount on one account, you will have a 1 BTC discount on each of them). If the arrows for increasing levels are not visibile, this is just a display bug; click on the right side of the box until you get to the level.
What is forbidden: self-referral, bots, paying people to use your referral link
My spreadsheet answers a lot of question about (increasing) profitability, number of clicks...
Tip: if the BTC difference between two levels are too high for your taste, you can by several account of lower level instead. Example; you have a 1 BTC account, you want to upgrade, but 5 BTC is too much - but 2 BTC would be fine. You can buy a second 1 BTC account, and you know have 2 BTC. If you want to move from 1 BTC to 1.25 BTC, it works the same - the granularity is 0.05 BTC, the lowest paid level (actually less, since there are discounts, too)

It seems btc-flow is lead by the same team that created cryptodouble.com (which was closed because someone on litecointalk alerted cloudflare)

Great list!

But where did you hear that about not referring yourself? I haven't seen that posted by admin.

I made a few adjustments to your spreadsheet. Thanks for sharing it
