No... seriously, the myth's validity isn't that unreasonable given adverse weather and certain variables.
For instance, taking the lid off to do WHAT? Spray relatively cool AJ on a rack of spares (as opposed to a big butt that's almost done)? Yeah, it doesn't take long, but in windy conditions it's sure not gonna help get it done by supper. As to the Minion method variable, I find that the most popular bullet fuel, Kingsford, doesn't really have time to spike in the time that it takes to just peek or spritz. Of course, if you've got wood on top of the coals that catches fire in that time, then you do get a spike.
