After some more research and doing a bit of math I do not think there is an advantagable edge here.
a hard one to grok.
It appears to me that it is possible to reduce the variability by hitting the button when one die is relatively flat and showing a particular number. The table only shoots the dice straight up.
Whether this actually makes a difference, I don’t know, but I did have an exceptional roll, and several rolls of 10+ shots using it.
I Also think there is a magnet, sometimes the dice will just stop suddenly from full motion.
