It might be a little unsymmetrical and likely represent the biggest change of aerodynamics since the stage went subsonic. Personally I wouldn't rule out a contribution to the need for the questioned "late maneuvering" (which might or might not have had extra control loop lag).I disagree with your deployment time. It's more like 1.5 - 2s.

Also, somehow it looks like this stage is descending at a much faster rate at the end, compared to Grasshopper. Can't they spare a bit more fuel to slow the vertical descent just before the end?It's like the equivalent of a guy screeching into his parking spot and slamming on the brakes.
An attempt at some color correction on the single frame:

Want to take that bet?How high was F9 when they called acquisition of signal at the barge? A drone at that height above the barge could transmit to the Cape, and other parts of the coast are closer / would need less height. Cheers, Martin

Cheers, MartinI doubt a drone could carry enough power to transmit back 300miles. Not at any acceptable bit rate.
