You use your words well. I am impressed and I agree. We are blessed in the modern age of watching people and their reaction to surprise ambushes and counter ambushes with the popularity of video surveillance. THe FIBS and FIBSA factor quoted by the active self protection guy seems to be strong determining factor in who will win in most situations. People rarely spend a lot of time working on time to first shot from a surprise encounter. From watching videos that and preparing for the first shot without drawing attention seems to be the best life preserving skills.
The quicker you end the fight, the less shot you’ll get.
