So why doesn't BTCGuild pay out all of your confirmed rewards?  Just another way for this non-fee pool to get a few more "involuntary" donations?  BTW, I already donate 1%.

Example:
Confirmed Rewards: 0.05029424
Hit the Pay Me Now button
Paid out: 0.05
Confirmed Rewards: 0.00029424

Why?  Why not pay me out all of my confirmed rewards?  Granted, we are talking fractions of a BTC here, but still...
