I'm pretty sure the lever ratio is linear. Half way between the suspension pivot and the wheel translates to 50% wheel rate. If it was the square of the distance, half way would be 25%. But your numbers sound close according to my butt scale.

By the way, what were you inputs to get "exact calculated"? Without a lot of very detailed information the wheel rate calculation is just a swag.
