I don't know if it will help you but I've got a milk crate that I stack boards on to for the proper depth. I can check depth in the mirror at home to see what makes the right height. On recovery or light days I take the crate to the gym and use them to pause on. I have to concentrate on many of the warm-up sets because it never feels like I'm low enough on them. Once I hit depth on those the work sets seem to be no problem.
