I agree with Bruno on the pasted strop being a crutch in the hands of a newbie. That is not to say that it is not a useful adjunct to the hones in the hand of an expert honer. I was taught to test shave at the 8k level to ascertain whether my honing was adequate to move on to a higher grit. I have made using the stones followed by the untreated strop the default method I use to get my razors shave ready. It has taken me many, many razors and a couple of years of doing it to get to a point where I feel that I know what I am doing with these things. For the first year + I went through the motions and sometimes I won and other times I lost without really knowing why. FWIW I have found that the 1961 barber manual excerpt that I frequently link to here is the method I rely on once I have set the bevel. Like any skill it takes a lot of practice to become proficient IME.
