If you marked the table like you were supposed tot was pretty fast and easy.I found it to make a tight rack, but didn't find it to be fast.
It wasnt so much the pushing the balls down as much as it was the rack being in the same exact spot every time. If you lined the rack up with the marks, the balls would settle into the same dents in the cloth everyt ime and the rack would end up being pretty tight.
I have one (the last model they made when the IPT was big) and found it great for practice. Same with the template racks, great for practice to give yourself a good rack without having to mess with the balls and kill your back leaning over the table.
