Default Throttle percentage ... linear or progressive?

Stock is a 1/4 turn throttle right... So that means 9 degrees of turn is 10% if it is linear....

Are throttle's linear? Or does it open the throttle increasingly fast as you turn the handle? EX... actual handle turns 25% of it's 90 degrees of motion... but only opens throttle 10% and if handle turns 50% of its motion its at 45% etc...???

I was curious after getting a bike tuned, (again), found that 20% throttle and higher was fine, but 10% and under were really rich.

I find it hard to believe it is straight, otherwise how could you hold a 2% 5% and 10% tune with such little turn.

I want to know so I can compare and potentially tune for highway cruising at a certain handle throttle position.

From looking at a Power Commander map, I would think it's combination of both..

TPS goes by (%) 2,5,10 20,40,60,80,100

Thats what I was thinking.. The way it looks, and it might have nothing to do with it, are the throttles designed the way that looks? like half of the total turn gets it to 20% and the other half goes to 100?
