I've rewritten the code to actually allow consecutive PoS blocks, but only give non-zero trust to the first one. Also, if my math is correct, YAC is supposed to have 144 PoS blocks/day (10 minute interval), not 720. 
I didn't know PoS had a 10 minute target. I thought the 1 minute block target was for both PoW and PoS (1440 / 2 (half PoS, half PoW) = 720 blocks per day). I get up to 10 PoS blocks per day - does this mean I'm actually am getting about 7% of the PoS blocks for that day?
If I'm understanding your last post correctly - does this mean (the change to the block trust) that we shouldn't see a difference in the way transactions are being minted currently? Basically seemly other then the wallet update?
I'll try to do some graphs on PoS block interval or something soon.
