Thanks, guys. That helps for when I decide on my next RDS mount. The old lower 1/3 cowitness is the max I’ll tolerate.

You look at current leaders in USPSA PCC division, two gun, three gun, and PCSL and you’ll see most running a similar lower 1/3 set up. From a performance standpoint that tells a tale.

Clearly all just boomers/fudds who don't know what they're missing...

The correct sight height is likely dependent on the shooter's body structure, personal preferences, and shooting needs. I don't get to excited about the mount itself, but rather the height of the optic's centerline over the buttstock. This is how I obtain a consistent cheek weld for a given optic across multiple rifles. Since my rifles' buttstocks are fairly consistent in height over bore centerline, my scopes' centerlines are generally 2-3/4" inches over center of rifle bore. This provides me with a relatively comfortable head & neck position for various prone, sitting, kneeling, and standing positions. I find that a slightly taller mount produces more of a light cheek brush on the buttstock than a firm cheek weld. Heavier cheek pressure on the buttstock regularly results in my throwing shots high, especially when shooting from less stable positions, such as from barriers. In other words, a slightly higher sight is more comfy and results in better accuracy -- for me.

I use only optics -- no iron sights, no co-witness. Irons & co-witness might be a little different for some.
