Did you have anti-flicker on? And didn’t use to have it on in 1dxii? That will always reduce the FPS to maintain correct exposure. I don’t have an R5 so don’t know how it behaves in anti-flicker situation. Even my older 1dx worked fine at swim meets.
You didn’t mention the behaviour of R5 in the same situation? If it’s giving you lots of long bursts, is the exposure changing significantly between consecutive photos?
Verified that flicker is off. No exposure changes between images. My 1Dx2 worked fine, so this a bit shocking to say the least. I haven’t tried the R5 as I simply can’t track using the mechanical shutter in this environment. The E-shutter is killing it though!

Just a thought I would never use single point for a moving subject. I would use either one of the area modes and choose the starting point at the head or face with the smart controller or at least use point with surround points. If using one of the focus areas I would turn face detect on. I would use case 2 so the camera holds onto my selected starting point.
Single point only and the smaller single point if I can get away with. The larger the number of points, the more likely the AF will grab water or droplets. I’ve tested this adnausem with the 1DxII, the III as best I can and the R5.
As a point of reference, the “learning database” in these cameras that’s supposed to find faces and goggles sucks. I’ve tried it on about 20 heats and it’s grabbed the water every time.
