Personally i hover somewhere around 150c/m, how long would i expect to wait for my first PTS?
Weeks, months?

No worries, i just got my first payout of 1.000xx something PTS. Have added a few  more machines i've got laying around and should soon reach 400c/m...
If only my Dual-CPU Quad-core 3GHz Xeon server didn't sound like a jet plane I'd add that as well...
