I run a blade until i feel its no longer working well enough. For me, typically this is 3 to 4 shaves. I can push further than this and have gone 5-7 shaves but its really not worth it for me and the shave becomes uncomfortable.
I will admit, on a day to day basis, I just wet my face in warm water, then work hot water into it, lather, shave and go. If I had time to go the extra mile then perhaps blade life could be extended.
