However, most of the runners on this forum are above average and probably have decent form already so it's easy for detractors to say forget about form and just run.
Instead of looking at metrics like vertical oscillation, etc, here is what I would suggest.
Video tape yourself front, side and behind running at race pace, tempo pace, intervals, etc in slow motion on a track (treadmills have a bounce to them.) Just have someone video you or put your phone on a stand and run by it.
Look for obvious issues that might need attention. Search for online advice and ask AI how to correct that problem or even if you should try to correct it. One of the problems with form adjustment is that changing one movement changes other movements up and down the chain so you need to be cautious about form changes. What works for most other runners *might* not work for you.
One tip: When you find something that needs correcting, work on it for only a few seconds at a time. Recovery runs are a good time to do 20-second "drills" of running with a form change. Run with the new form for 20 seconds and then run normally to fully recover and then repeat a few times. Over time, you can add to the time and make it your new form.
Sudden form changes can result in injuries, even when the form change is to reduce an injury someplace else.
