Math is suddenly taking a beating.Take that same 15,000ft flight where the rocket is a half mile downrange at apogee, and a strong wind normally could have pushed it another 1-2 miles during its time under the drogue and chute. If a steerable drogue would even just halve that downrange drift it's a significant improvement.
With a 1:10 glide ratio it is only going to reduce the recovery distance by 1500 feet which is significantly less than half a mile.
Plus, a drogue is only used for only part of the descent, you have to subtract time for the drogue to deploy and orient itself, and at typical drogue descent speeds it may be very challenging to make the rig stable and steerable.
That's why I was suggesting that a quick descent under a drogue parachute might not be compatible with a controlled descent.
The same issues, of course, would apply to a larger parachute and slower descent. But, assuming the rocket flew into the wind, the slower descent rate would allow it to travel farther back to the launch site and I would think the challenges of deploying and controlling the descent would be easier.
