Since the clutch master output port is on top of the cyl. if you put fluid in it should run fight thru and come out the output without doing much bench bleeding. As long as you have the out port the highest point and open fluid should run out and you should have most of the air out of the cyl.
Brake masters are different since their ports are usually on the side and air sets in the top of the cyl. so they gain from a bench bleed.
Takes my experience on it anyway...
