So there's a real trick to it then! Figure out how fast your card burns through the longs and wait until one under the time from the start of the challenge to start running wu's. Good thing to know. I managed to pick one wu up and it's 3 days until the start. I'll have to see how long it takes. I think I remember my card takes about 14 1/2 to 16 1/2 hours to complete a long with my nvidia card. I'll pick up a second around 20 hours until the start unless I just let the one I'm running now report and pick up my next around 30 hours til. Still gonna have to babysit to make sure to get that second one within the last day before.
