For the benefit of those of us not experts on unusual attitude recovery, I found this interesting.....
"The second benefit of unloading the wing is that the aircraft’s roll rate improves dramatically. You will lose less altitude when recovering an inverted, nose-low airplane by pushing to near 0 g, rolling crisply to right-side up, and then pulling to level flight. This holds true even when you are significantly nose low. Where a typical business jet can take 5 sec. or more to roll upright with 1 g or more on the wing, the roll can be completed in 1 or 2 sec. when closer to 0 g."
