So - how do you all practice on deadbolts? I think I've spoiled myself by practicing like this:

Unfortunately, either it's not possible or I've not figured out yet how to get anywhere near the tension and pick control when picking a mounted lock. Am I doing myself a disservice to practice with the lock in hand as shown? I've got a practice 3-cylinder stand, but it's really lightweight and has been a pain so far.
How do you all practice your deadbolts?
Many thanks.
