I have been reading this thread for a couple weeks...interesting to say the least.
 
I have a problem trying to figure out why my reject rate is so high. When I check my individual machines my reject rates are 0.003664
0.548387 & 0.002722 but it is reported as 0.2237 sometimes it even goes over .3 so could someone tell me why the huge discrepancy? WU on each machine exceeds 94.
