Minting coins destroy coin age of the stake, you have to wait another 20 days after a successful mint (in a few days, the top 2 transactions that occured on 14-04-14 will become eligible again)
Thanks, thats lame indeed, but that does not explain that 200 days
200 days is in tooltip because currenty you have only about 6 coins participating for mint. 20% yearly from 6 coins is about 1.x coins per year. This amount is in absolute bottom of priority list.
Soon you will have larger amounts rolling for mint and tooltip will change to lesser time, since it takes average of all coins which are participating for mint.
OK, it makes sense this way, thanks. Anyway with all this fuzzy rules whole POS looks like some kind of woodoo...
Yes, they told that same about WhiteCoin
