How common is it to see a shock dyno is the pits at a drag race? How many have them back at the shop?

I know in our local Circle Track racing, 20 years ago having a shock dyno was un-imaginable for a local non traveling team. Maybe a couple traveling teams in Winston West (one under Busch) had them. 10 years ago, a few local teams had them. Now many have them. Shock tech has gone up and shock dyno prices have gone down.

Wonder if shock dyno's will get more widespread in Drag Racing too?
