No, it most certainly is not a fighter. But we have gained ~2000 feet in pull out altitude from the initial cut at at the pull out. We haven't even hit the cornering speed. To avoid secondary stalls, we are likely to have to give some of that hard earned altitude back.
If fighter maneuvering theory helps, we should understand the theory. Far better to pull out at +100 feet than -100 feet. When your life is on the line, you may have to walk a delicate line between not making a fatal maneuvering error (secondary stall) and achieving maximum performance. All this while your heart is beating 10 miles per minute. Give yourself as much leeway as possible. In Alternate law, you govern the AOA. Don't mess it up!

Yep, but it will roll on you if you tear one off. Best bet is to leave them in. The fewer things you have to do during the critical pullout, and the fewer risks you have to take, the better.
