For concealed cary I actually think 4 to 7 yards is more realistic and more better. I also think shooting one handed with both strong and weak hand, moving to shoot, turning 90 and 180 degrees, shooting while seated, kneeling and prone, multiple targets, shooting while moving, barricade, reloading (speed and tactical), shooting from cover and concealment, and low light with and without a flashlight, are way more important than keeping all your shots in 3 inches at 10-25 yards. And all from the holster you carry in, of course.
Add scenarios and this is a pretty good defensive pistol curriculum. My sage advice is not to move back to 10 yards until you can do all this confidently from 4 to 7.
If anything ever does happen it's likely gonna be up close and fast, and very likely nothing will be standing still (including me), so be realistic in your training.
