It doesn't seem that you have any adjustment of the elevation, and that you
are just going to drive the azimuth.

If that is the case, why not just drive it from a clock, ie the azimuth
angle calculated or looked up from hour of day.

BTW, this is hardly an optimised pointing.

You comment about 15°/hr is applicable to an hour angle / declination
mount... but that isn't what is in the picture.
