How to start from the step where you left off in the input range?

Question

JavaScript

Good evening, tell me the algorithm for saving a step in the input range, so that when we move again, we take into account the previous step.
In my example, if you move the mouse up or down along the height of the block, the step in the input range changes and the scaling factor is calculated in the range from 1 to 3.
The formula is not exact, but in my project it works correctly, here in the example I hardcoded, so don't go too deep.

It is necessary that if you move the mouse repeatedly, the countdown starts from the place where we originally stopped. Now it twitches and starts from the place where we clicked. Thank you!
