The only thing I will tell you is that when I started with a straight the first week shaving I was very happy I didn't cut myself and get massive razor burn. A shave approaching decency wasn't even in my vocabulary then. It was two weeks before the shave was reasonable and a month before the shaves were decent. it was 6 months before I was getting really great shaves and almost a year before I had real facility with the razor and somewhere between 6 months and a year before I was getting BBS all around.

So take this the way you want. It just takes practice and lots of it and you need to vary your technique.
