I have real test experience with this. I can tell you that at 300 feet when the engine quits there is just enough time to cycle the carb heat, cycle the throttle, check the fuel selector, make a radio call, find a brownish area in the dark, and land with the flaps you had when it quit. This occurred all in about 15 seconds. The stick was full aft ( had to clear a ledge to make the brown area). Forward speed calculated after the fact was approximately 66ft/sec and vertical speed approximately 13 - 15. Ft /sec. The aircraft with wheel penetration skis came to a stop in 75 ft. on semi wet grass.
The VGs kept the machine from stall spinning, which would have been the case with a slick wing. The VGs in the power off condition kept the aircraft controllable laterally and never let the nose or wings break. It mushed in a fully developed sink.
All other options were unavailable. No altitude to convert, no time to pull full flaps for ground effect,no charts to look at, just eyeballs, stick, and feet. I just had to fly with what I had left.
