Lohoris,

I believe this is what you are looking for;


"DIVIDENDS FOR DMS.SELLING

Whenever a DMS.MINING dividend is paid an assessment will be made of whether a DMS.SELLING dividend should also be paid.  This will be done as follows:

NAV/U post (DMS.MINING) dividend will be divided by the dividend just calculated for DMS.MINING.  This produces the number of days at current difficulty for which dividends could be paid from current capital.

If that number is greater than 410 then a dividend will be issued for DMS.SELLING (and any outstanding DMS.PURCHASE) such that it would reduce capital to exactly 400 days of dividends at current difficulty.  If the number is less than 410 then no dividend will be paid.

This serves to keep capital at around 1 year's dividends (the buy-back price) plus just over a month extra to allow for short-term variance in difficulty."
