I came to the same conclusion. As I improved in my rile shooting skills and after experimenting with a few different LPVOs I decided that inside of 200 yards a dot was still king of the castle if I cared about getting shots on paper as fast as I can and not shooting the smallest group I could.
For me 200+ yards is where the LPVO starts to offer serious benefits and because I don't have an opporotunity to do that all too often and because realistically if I need to use a rifle for defense it's going to be well inside 50 yards I run dots on most of my guns.
I say 200 but it's more like 200-ish depending on the day and how rusty I am. Realistically a sliding scale based on how large the target is, how tired I am, how heavy is the gun, how hot or cold it is, is it the start or end of a shooting session etc.
