Take cheek weld for example. With irons, a consistent chekweld is essential while with a RDS head position has broad parameters. Putting your head in the same psoition makes putting the dot on target very natural and easy. While varying head position complicates finding the dot on the target. When fractions of a second count, simplicity reigns supreme.
Or, you could choose to address this from the opposite direction, if we're going to focus on HD/SD and what people choose to practice with when they go to the range.
Cheek weld means nothing for using an RDS at close ranges for HD/SD, where speed is king. So, don't bother wasting time and money with irons, focus on training with the RDS you would actually use.
Worried about finding the red dot quickly? Practice it. No matter what, you'll be far, faaar faster aquiring your target with a RDS than irons. Hell, the uber competetive AR gaming shooters don't even seem to use any cheek weld at all.
If find it a bit disconcerting that some fail to understand that most people's time and money for shooting is not unlimited, and is best utilized by focusing on what you would really do in an HD/SD situation, if that is what we're to focus this discussion on.
