Was it settled on that the official multiplier for the Pocket camera is 2.88?
That seems low to me, and others were throwing around the 3.5 number.
Do we have a definitive and final and perfect number for the Pocket camera?
It is 2.88x if you compare to a full-frame sensor that has the same 16:9 aspect ratio. Since the aspect ratios are then normalized to the same value, it is easy to calculate accurate crop factors as you only need to divide the width of the BMD camera sensor into 36mm.
Another way to calculate the crop factor would be comparing image circles but that is misleading since you are not going to deliver a video in the aspect range of a full-frame sensor (3:2). That's the way I see it.
