Spurious payout message

[mburns08109]

For some time now, my stat page has been reading as follows:
"Estimated Position in Payout Queue
Approximately 0.00000000 BTC remaining to enter payout queue. Maintaining your 3 hour hashrate average, this will take at least another a few seconds at current network difficulty of 47,427,554,950.65."
...and it has not changed in over a week.
Is this a symptom of slow mining with low power and a numeric precision limit sort of thing, possibly?
