The good and bad of R comps at the track

I sit there and hand-turn the lugs down to initial snug and ensure the wheel is flat and the cone seats are centered first. Then I do a star-pattern with a regular wrench and ballpark them to ~40-50 by hand, then go back over it again with a handheld torque wrench to 85.

Then again I've seen trackside shops toss a wheel on a car and use an electric impact. They put all 5 on straight to final torque one by one and they're done, and I guess they assume everything will seat itself given sufficient torque. I can hear clicks like an automatic torque limiter, but I don't know if that's in the gun or in some socket-adapter? When I try googling, I never turn up much except those solid torque-limiting extension sticks, which I'm guessing just flex when they reach their limit.

They drive just like a car .... example here ... Ford Australia - Ford Falcon or Holden Ute - Safety - 2014 - Australia

It's one of the normal ones you find at parts stores, and I have to first reach under and fit a little adapter onto the pinch weld. I should look at spending on a proper racing jack, and maybe welding some little flat plates under the car along that pinch-weld area and marking them with arrows on the rocker panel so I can just shove the jack under and pump 3 times and be done.
