I think the cloth speed is better expressed as the reciprocal of the equivalent uphill slope that gives the same deceleration. That table is about 180. Pool tables are about 100.
Some people like to know how fast the cloth is. They want a number on it. Some people don't care.
If you can produce a constant or equation than I can add an option to display with that value also
From the number you have, it should be easy to calculate the deceleration, in m/s^2, of the center of the ball. The slope is just that over gravity, and then take the inverse to get a number of around 100 for table speed. (This ignores angular momentum, but it's simpler.)
I am getting rot_decel x pi x ball_diameter / (4 x table length). This matches your numbers, so the numbers in my video are wrong. Should be around -0.27 rps/s, which is close to 0.5%-jewetts.
I'll fix the error!
—note to self: forgot to scale by N/timescale
— ok, video has been corrected!

I'm just glad you used his last name to name this measurement and not his initials... I can just see pool players discussing the +/- 1.5 BJs.
It depends on the notation, like Calories and calories.
A small jewett is 0.5 and an equivalent big Jewett is 0.005.
I just wish that I could buy a Digiball.
Dont we already??
