Last to bend is first to straighten on release. The inner part of the bow is all torque, and the outter limbs is all horsepower. It takes torque to get a car off the line, it takes HP to get it there quick. So ideally, on release, you want the limbs to lool like they are doing the wave, starting at the fades and moving toward the tips. The inner third gets the arrow moving, mid limb is mid range, and outter is top end red line.

I'm not sure about last to bend, first to straighten. When you pull a bow, even just an inch or so, the whole limb bends. The outers bend more, of course, but the inners bend too. Same on release, I think, the bow doesn't unwind, it all starts to move at the same time. I'm not so sure if it finishes at the same time :D

The arrow keeps a load on the bow limbs, keeping them from sprining loos all at once. The heavier the arrow the more effecient and thays why.

This is all my take on this so far, opinions will vary.
If you accept that the nock can move differently than the bow tips. Say at the beginning of the draw the string moves 5" for every 1" that the tips move but at the end of the draw the string moves 2" for every 1" the tips move. (I picked the numbers out of the air) That's a 5:1 ratio and a 2:1 ratio. It's not a real stretch to compare that with changing gears in a car. Some bows will be closer to 5:1 through the whole draw-- a low gear bow, and some will be closer to 2:1 through the whole draw-- a high gear bow. I think I would have chosen "high ratio bow" rather than "high gear bow" but that's just semantics.
Oh, I don't know who chose to use that term to answer your question ;D
