When the mound was lowered, the slope remained the same. In other words, the higher mounds were not any steeper than than the lower mounds.

The height of the pitcher's plate has been changed at times. If the slope in front is retained at 1 inch to 1 foot, the height is almost irrelevant to the pitcher-batter competition. A decrease (or increase) in height of 2 inches is then precisely equivalent to an increase (or decrease) in the height of the plate - and the strike zone - by 2 inches, and the effect is that of making the pitcher throw each pitch 2 inches higher (or lower). However, if the slope is changed and the pitcher's foot lands at a different height, the leverage of the pitcher will change, and that can affect the delivery.

It's all explained - just like the myth of the "rising" fastball.

On the other hand, the advantage of a scuffed baseball is real.

Oh-oooooo! The rising fastball has surfaced again!
