1,3 percent POS every 20 days. This is just superb. It looks like it works better than mintcoin (I mined that before Zeit), but I'm not sure if that is possible (as they probably have the same codebase).
Anyhow seeing the POS coming in is great.
From my personal experience, I saw that Mint has slight problems with Minting. The minting process is not as accurate as with ZEIT.
Whereas all of my mintings today with ZEIT were almost exactly after the sums aged for 20 days.
