I am noticing the more I use a particular razor, the more my results with it improve. Obviously, this is different for all people and razors but I was wandering if the long-time users have observed a "rule" - e.g. a minimum of XXX shaves to develop a feel for the razor, etc.

On the other hand, improved results do not have to equal increased enjoyment from the razor. With some of my razors it just seems I don't enjoy them as much as others.

How about you?
