Is my shaving skill/technique getting better or is my skin becoming conditioned to the straight razor?

After alot of shaves, gradually I have become able to shave over the feared chin and upper lip without incident. I suppose there may be alot of factors involved in my success.

Possibly:

1) I am getting my razors sharper with improved honing/stropping.

2) More experience shaving.

3) Facial skin is getting accustomed to the SR.

I think #3 if a big factor and a little underrated. Beginners should consider that in time a nice shave seems to happen all by itself (well almost). It has taken me a couple of months but it seems that my skin is accepting the edge of the straight razor much more readily now than when I first started.
