Not my tool, so no idea how to get at the data... but changing the wording on the page to something along the lines of "your reward will be placed in the payout queue once it crosses the threshold" could be a start, and maybe followed by "click here for an estimate of the payment progress".
I'd recommend "This amount will be
eligible for payout to you when it reaches approximately 0.33554432 BTC or after one week of inactivity. Eligible payouts are sent 50 BTC at a time when the pool finds a block, oldest balance first.
"This amount will be

I think that's the most informative/concise wording I can come up with. Also, does it need "approximately" when the amount is specified to eight decimals...?
