Method Shaving, Cutting Forms and other questions

[Kaifa]

Some little questions from a forum newbie :

1- What is "Method Shaving"? http://www.youtube.com/view_play_lis...B8DD0B02808245
Apart from the different products to produce lather, I don't understand what's the difference with a traditional shaving

2 - These Cutting form: http://www.enchanteonline.com/pages/...ttingforms.pdf
I just tried this morning to be more precise in shaving, and to give regular strokes in particular order and not the usual chaotic way with many different angles at the same time. I found the Q3 in 2nd form really impossible (for me) to do with straight and in the "method shave" video in fact they do it with a safety razor. . . Do you use that or shave only following grain and against grain?

3- Do you usually swap hands from side to side?
I'm left handed and till now I've been using only left, with an obvious difference between shaving a side from the other (different angle and position of the blade). In order to have a more scientific shave I decided to swap hands to do exactly the same strokes on the left and right sides, but using the right hand was very complex and I felt unable.

4- Last stupid question is: I know people lightly slapping their face when applying an aftershave? Is it useful to improve circulation (and even covering a razor burn) or only an unuseful act?

All the best
