depends on the results. there are many causes for a delayed start. Gun sensor may be bad. radiolynx might have a low battery or loose wire. you may not be properly aligned to where you placed the gun.
IMHO, there are too many variables to cause you unnecessary grief than its worth. I've never had to do one and my camera has a scope so i know its on the line. I do sensor tests before every meet. In all my 20 years of using Lynx equipment, i've never seen an "uncalibrated" camera. Sensors on the other hand go bad, get wet, or lose their sensitivity. Lynx usually ships the gun sensors with a rubber cover on them to protect against water, this can cause it to not trigger a start, i tear it off any I see and they work much better. The only calibration mine ever needs is to verify the scope (TTL) is aligned.
