I’m considering a RMRcc for my Glock 26, but after running this Holosun 407k with manual brightness only, I’m starting to think about the importance of auto adjusting.

This is for my daily CC and it’s also my idpa gun. I’m a middle of the pack shooter with draw to first round hit around 1.5 seconds.

The reason I bring that up is, does the adjustment actually keep up with a shooter’s draw stroke. Or is auto brightness just a sales gimmick?

I got couple of RMR HD's. 85-90% of the time auto-brightness is spot on. Much better compared to regular RMR auto setting.
 
They work pretty well most of the time. It's a trade off really, you can run a manual brightness optic really bright to make sure the dot is always there, but in some situations it's going to be too bright, or you can run the auto brightness but I've found they can be too dim in some scenarios.

The two scenarios I've seen that confuse auto brightness setting optics, some do better than others: 1) if you are shooting at a covered range outdoors and you're in the shade but it's super bright/desert etc. the optic can select too dim of a setting. 2) If you are shooting at an indoor range that has a darker target area, but brighter lights around/above the shooter the optic can select a setting that's far too bright. Basically anytime the shooter/target lighting are significantly different the auto brightness optics seem to struggle. Usually you can still see the dot, it's just not ideal. Most seem to adjust extremely fast and I've never had one when drawing or even shooting on the move did not adjust more than fast enough.
