Hey, there!
I just posted a video that shows three days dressing the AVL production dobby for a 175-yard beam. If you look really closely you can see things like how I separate heddles as I thread to make sure that each pattern repeat is threaded correctly before pushing them off to the side, how I double-check threading while separating threads into denting sets and laying them on top of the shafts for lightning-fast sleying, etc.
I made sure that I did two things:
1. Photographed whenever I was working for three days so there's no "missing time" from the work.
2. Kept the frame rate constant. (12 real life minutes per second of video.)
This lets you judge for yourself just how fast each part of the process is.
Enjoy!
