Tamron 70-180 Tracking at 15 fps on A9

Can it track and shoot at 20fps on a9? i know not all lenses can keep up with a9 at 20fps. please let us know.

Good news: tracking works fine at HI setting, at least on constantly moving objects (car at 40 mph). Also seems to track well while zooming (not shown in this sequence).

Bad news: HI "only " works at 15 fps. Which is still enough to generate a movie.

First shot in sequence, full res

Last shot in sequence. Focus point remained on the front grill area and/or left headlight (right, from photo POV). Pixel peepers will notice some CA on the grill.

In this 55-frame sequence during which I zoomed from 180 down to 70, there were three frames out of focus, marked in red.

Including first, last, and a middle one for comparison:
