yes, i've seen other recommendations to use something like c1, but i didn't recall seeing anyone say to turn off subject detection in conjunction.
I've advocated not using SD in many of my posts. I use a large single point AF with no SD with my Fujis for rugby and it works really well. Been shooting rugby for 8 years, started with Nikon D810, D850 switched to Fuji XT-4 and and now Fuji XH-2s.
