I thought I was losing certain shots to shutter shock or missed AF until I switched to the A9iii, and it became blindingly obvious SS was too low in certain situations because the A9iii AF hit rate is like 99.9% at high SS, the camera has no shutter and yet some shots in a burst sequence were still blur.
Some of my mental shutter speed "look up tables" learned when shooting a 4 / 6 / 8MP cameras had to be un-learned.
If you are shooting BIF start at 1/8000s. If the light sucks you can use 1/3200s but expect some shots to be blur.
I also made a post about how AF at 200/2.8 is considerably better than 200/5.6. The amount of light hitting the sensor does make a big difference to autofocus performance on mirrorless cameras.

I thought I was losing certain shots to shutter shock or missed AF until I switched to the A9iii, and realized that my shutter speed in certain situations was just too low...
