there is an interesting a strategy on page 23 where they suggest shifting the entire hand when typing TGB/YHN rather than stretching. Does anyone do that today?

I just tried a bit of typing where I shift the entire hand for appropiate keys rather than stretching my fingers and although it is a very unusual feeling I must admit it is quite a bit more comfortable. The fingers stay curled rather than being stretched out. Did I just get an epiphany from typewriting tutorial written in 1894??
