I am trying to make the results page percentages match my actual results in a spread sheet and definitely having trouble matching them up.

Probably calculating it wrongly, anyone manage to make that work?


(BTC total) - (daily amount earned) * 1.0(% of that days return)


I am computing (today's balance) * (results percent) + (today's balance) == (new balance)

For example:  bal = 1.0 BTC, results = 2.34%
1 * (.0234) + 1 = 1.0234

It is not modeling correctly in the spread sheet.  It looks like rounding errors.  I think they are rounding up their results percentages.  I've repeatedly asked them to provide higher fidelity data and/or CSV downloads suitable for putting in a spread sheet.  Those support requests have been ignored on every account I manage.

I will be reducing my exposure.

If you look at the entry on the calendar for 01 April you will see that the percentage is being calculated to at least three decimal places but is being reported to two.

I suspect that the developer is rounding up to the next higher place in the second decimal place rather than doing true rounding.  That would explain the problems I am having getting things to match up.
