thanks for the reply burnt toast. I had found the info youve posted above when i had google searched days ago but i wasnt sure how up to date the info was for 2012 so that was why i started the thread. Also about the 45ml is good enough, the testing facility i was at was very busy with 5 small cubical booths for collectors with 5 small bathroom doors accross from each booth where i could see other donors going in and out of there bathroom doors and one donors cup i saw had a sharpie mark up almost 2 inch which was where the temp strip was on his cup(roughly 3-3.5 oz) my guess,, these were pretty big cups probably to prevent spillage. But my cup and one other were at about the same spot where the temp strips were and the sharpie marks which was around 1 inch up on the cup.. temp strips were not perfectly straight sideways on cups either.

Basically im saying these collectors or whoever was making these cups was kinda just stickin the temp strip wherever which resulted in more and less pee needed.. i would be scared to enter without 4 oz just in case.. I would hate to have to raise hell at the facility cause i only brought 2 or 2.5 oz of subsitution and couldnt get it to the temp line
