What we should do and what we would do are rarely the same.
I practice extended arm shooting. I compete with mostly extended arm shooting. I know inside a house etc. you need to tuck your arms in, and was taught "hip" shooting 20 years ago.
But if it came down to reality and muscle memory it would again end up extended arm shooting even at that range.
But I think in the reality of a situation draw what you can and stand how you can. The situation will dictate everything before you think about such niceties.
