Absolutely.

Undoubtedly three sensors are better than two but because of location and the particularity of AoA measurement, it is not foolproof in the way that three temperature gauges measuring temperature at the same place would be.

Also more complex algorithms can introduce another failure point especially in a processor which it has been claimed is running close to capacity.
