IMHO as a miner I'd like to have enough hash power to receive a payout from each block found.
The minimum estimated hash rate to have an expected payout in each block found has gone from ~40GH/s about a week ago to ~50+ GH/s today. Even at 50 GH/s you may skip a block or 2 along the way, but your still getting a payout in the majority of blocks.
3 Easy steps to estimate the low-end of hash rate to have an expected payout in each block:
1. Go to http://minefast.coincadence.com/p2pool-stats.php
2. Click on the "Active Miners" tab below the graph
3. Click on the table header "Est. Hash Rate" to sort by hash rate
You can further investigate by clicking on the dashboard icon and viewing the miner dashboard.
Keep in mind these are rough estimates of hash rate for each miner in the pool, and that the estimates are subject to variance/luck (if your estimated rate is higher then your actual you are currently lucky).
. 
I'm just wondering at the sudden and abrupt change in the amount of the payout. I've seen my payouts change over a multi-day period before, due the variance in finding shares with my relatively small 200GH or because I go through a period of downtime for a few hours. I've just never seen it drop by an order of magnitude in less than a day before unless I had completely turned off all my mining rigs.
