For those of you that have received stake, what is the smallest transaction amount that has staked. I have about 20 x 5.xxxx coin transactions about 32 to 33 days old but none have received pos yet

Not sure - most of my transactions were 10 coins. The first couple days of stake were quiet, but they started to come in quickly on day 3. 32 days before I started to see a bunch.
They're still not as rapid as the initial mining quantities. I have ~500 transactions over 30 days old but only 30 stake transactions so far. I've had 5 stake transactions in one hour, but average probably ~2.
