There’s no way your shots will be faster if you’re feeling without looking. At night if you aren’t able to light up, you may have to. But that’s when the necessity trumps speed. And if you’re in situations that require this, you’re better off with MTC that allow you to dial to the nearest whole mil and then make a small holdover or under from there.
And as far as second guessing what you see, I’m not even sure what that means. If I dial to 7 mils I’m not thinking “wait, that didn’t feel tactile, am I actually at 7mils?”
There’s very few situations where the need to stay on glass while you count clicks fairly slow is going to be a better option than taking a couple seconds to look up. Not to mention you can usually do it if you have both eyes open anyway.
