How does the variable HE work? It's not explained in the FAQ.

Is it random, or does it increase proportionally to the potential profit? Do I get 0.5% HE on bet with minimum profit (1 satoshi) and 1% on max profit, or is there a fixed bet/profit amount after which I get the 1% HE?

Anyhow, the "0.5% House Edge" in the title and "0.5% Variable House Edge" may appear intentionally misleading, it would be fair if you change it to "0.5% - 1% HE".

I like the simple, minimalistic design tho.
