What impacts bend distance:pitch change ratio?

Taking out of the equation a floating bridge where you have to overbend to compensate for the bridge moving towards the nut as you bend the string, I've noticed a few other things recently. Any others? Am I crazy about the following?

Wound G-string -- pretty much limits your ability to do more than 1/4 step bend. I'm not talking stiffness here (though the wound G does seem a little harder to displace than similarly gauged plain?), it just requires one to move the string so.far. to get any real pitch change out of it that anything beyond just massaging from a minor 3rd up towards, but not to, the major 3rd feels out of the question on a wound G and even that can be a struggle sometimes.

Road Worn tele with 7.25" radius feels slinkier to bend strings, but also feels like I have to travel a lot further to get similar change in pitch compared to my K-Line w/ 10" radius and same strings. I can kind of see how the geometry would make bending on a tighter radius to require less force -- as you bend the string its coming back closer to its rest position in plane parallel to the neck. But it seems surprising that this alone would have much impact on pitch change per unit of bend displacement? Seems like if it did our guitars in general would be wildly out of tune when fretting.

I feel like the same kind of thing happened when switching between top and bottom wrap on my SG -- yes, top wrapping felt slinkier, but it also felt like I had to bend the string forever to get a whole step.

Is there a general rule that (again sticking to fixed/decked bridges here) that the slinkier feeling a string is, the further one has to bend it to get the same amount of pitch change as a stiffer feeling string?

Maybe I'm just completely nuts.

Curious in part due to Jimmy Herring's report of developing tendonitis issues when going from fixed bridge back to floating due to the need to bend more aggressively to account for bridge float. Already have enough tendonitis issues that I'd like to minimize any other possible sources.

I will do you a detailed answer but just for now ; radius has nothing to do with string compliance.
 
The amount of dead string to the ball end and tuner plays a part either big or small depending on the break angles and how much it can move. Add moveable string to a small degree and it makes the string feel less rigid but need more distance to achieve pitch. Think top wrapping a tunamatic. You quickly get to a point that tightens up and starts to feel tighter if you go longer. Think shallow Strat trem block with five springs.
 
Separate but a huge effect on feel is action and fret hight. These equate to grip. The tension is obviously identical for the same string type on the same scale tuned to the same pitch but it can feel very different. Compliance is entirely down to how much the dead string can be brought in to play and how much force is required to do so. This and the scale length/ tuning. Now add the grip that your setup and fret hight allows and you have it. The only setup that would get the minimum possible compliance is a Floyd rose locking system with the trem function blocked. The dead string here would be clamped out of the equation.
 
The part where you bend it.
