Yep, that would be ideal.
What Dennis should do is offer a couple people a few pool lessons if they will rack for him on dual tables like that. 3 hours of racking gets those two an hour long lesson.
Continual breaking like that is exactly what Dennis needs to work on the weakest aspect of his game.
Actualy the racking part is critical ,, he would be better off having someone video taping it then review , break more then review more ,,could even use a break app to find out what speed works best ,,
