I am not promoting or recommending you do this but here's what I do.
- For new skis/bindings bought from a shop (rare for me) I will have the shop install/adjust/test once.
- For most skis/bindings I buy used or mount my own bindings: No formal shop calibrated testing. (I do my own "functional" test -- uncalibrated).
- Ongoing I test by skiing. I will re-adjust if I get new boots or have some pre-releases.
- I don't re-calibrate and test my car's airbags -- I trust the QC of the bag manufacturer to keep the sensors and trigger point within the control chart range. Similarly for bindings. I trust the manufacturer to get them close enough that I can detect a malfunction using living room functional release testing.
- The cost (if it is indeed $60), would often times be 50% of the used-binding purchase price. Not worth it.
- I have enough experience using, mounting, adjusting bindings for me to feel comfortable doing this.
- I believe that most of the problems found by calibrated testing will be problems of boot/binding/ski mounting and compatibility -- i.e. functional problems. Actually finding that the binding system is set up and installed correctly, yet the indicated release value is far away from the acceptable range should be rare. (Based on my belief that the binding mfg QC is adequate to ensure this).
