Jun 9 2014 2.06% 142.75%
Can you please clarify this? You said there was a 5% retention (ie. house edge) but the profit was only 2.06%?
Sorry if that was confusing. Over the week, the amount wagered was 17754.48434936 BTC and the profit from that was 962.1460573 BTC. That profit is 5.419% of the amount wagered.
Through the week, the size of the bankroll was around 46k BTC.
If you were contributing to the site's bankroll for the whole week, your contribution will have grown by 2.06%.
The 962 BTC profit is roughly 2% of the 46k BTC bankroll.
Note that I did write I was listing "the 10 most recent weekly returns" - return as in the percentage growth experienced by anyone contributing to the bankroll that week.
So there are two different numbers:
* 5% : the effective house edge (profit as a percentage of amount wagered),
* 2% : the return to investors (profit as a percentage of the bankroll).
