"Personally for me, I would probably not draw (i.e. let someone know I even had a gun on me) unless I was 99.9% sure I was going to pull the trigger as soon as I got my gun into position. Yeah, there’s always that 0.1% chance things might change though, so that has to be taken into consideration."

But that's just it -- in the majority of cases, things DO change when a weapon is drawn with the intent to fire, in the typical scenarios in which law-abiding citizens are forced to draw a weapon to defend themselves. We're talking thousands of times a year. Definitely do not draw unless you intend to fire. Definitely do not fire just because you drew your weapon.
