Ok - follow along for a second.

Last POW block was 25000.

Maturity of that *last* block will be at 26200, right?

Current block as I write this is 25829.

So with POS moving the block chain it's moved 820 blocks in 24 hours meaning it should be another 12 hours (approximately) before that last mined block matures.

If you wanted to do some math you could figure out how many MASTs exist from mining waiting to mature and get an idea what's left assuming a 100% sell at the current price at maturity.

This means there's still a bit of mining proceeds waiting to mature out there and the dribble of dumps will continue.

When the block chain hits 26200 + another 12 to 24 hours... then we should start to see what's going to happen as the miner's influence ends.
