Folks who are using the current gen OM Systems bodies - how reliable is the eye or subject detection underwater?

The OM5 doesnt have animal subject detection but does have eye detection. The 1 and 3 bodies do have animal subject detection.

Any first hand experiences on how well these work with moving subjects where lock/recompose isnt always an option?

TIA!

I haven't used the OM1 II but the original OM1 has some of the best tracking of any camera i've used. It is remarkably sticky
