I have read from one of the reliable instruction sources on the internet (dont rember which one), that you should not stropp when you shave. That the steel changes molecularly slowly and you should strop no sooner than 24 hours before using the razor. I know a little something about steel and this makes very good sence.
That being said, I take it with a grain of salt. I stropp a bunch of razors on sunday, I stropp sometimes the night before and I stropp just before and during my shave. I have had equally good results with all methods.
I say do as you think will fit your schedule and your pleasure.
