All of this, and no mention that RTT is a very poor performer on the R4? Strongly suggest not even bothering with it, you're better in Wide 99% of the time. The A9/A1 changes the formula substantially.
I would go even one step further and say that I never even liked using RTT on the A9/A9II. At least for BIF or other moving subjects. I did use it for perched birds some of the time. Now with the A1 I'm using it a bit more for BIF but I still prefer Wide and Zone (without tracking). I do use RTT for perched birds most of the time on the A1 as my Custom Set for perched birds uses Expand Flex Spot: Tracking as its recalled AF mode (along with lower SS, Auto ISO, 10FPS).
To be fair, I doubt it was ever intended for subjects as erratic as birds. Works well with people, cars, etc.
Don't use my A7RIV for BIF, but for these "Tbird" photos the RTT, Zone and AF-C at low or medium is the cats meow. My hit ratio the last year with aviation photo and the A7RIV / 100-400mm GM is over 90%. Taken last Saturday, just over 1,000 photos and never had to focus once, the dancing dots did all the work.
