I typically average when the object is away from meridian passage. Even then, a quick series of shots means less change in the object's actual rate of altitude change over time - I will do 7-8 shots in 4 mintues or so with good results. Near meridian passage I will shoot a series quickly over a longer period to see both the rise and fall so I can figure the time of local noon with a reasonable amount of accuracy.
At least, that's how I have done it but I can't claim to be a professional navigator! I do this from my backyard and it's not moving - the practice is fun and my goal is very high accuracy.

I suspect he would but it might not be cheap. The mount takes up a fair amount of material and takes quite a while to print. However, I will ask. I know that he would be willing to share the raw input files so if you have a 3-D printer or access to one, it would get you there.
Pictures of the mount included. If you are interested, my personal email is cnavSpica at protonmail.com
