// kalman filter is calculated but not actually being used.
// the problem with this kalman filter is that it assumes most simplistic situation:
// 1. the actual delta (measured delta - noise) is constant
// 2. everything is linear
// we may need to implement Extended Kalman Filter but wtf is Jacobian, I suck at maths.
// Instead, the kalman filter will reset when new delta is given-value-times greater/lesser
// it's not perfect but it works.
