I believe we have defined a soft cap as two different things in our respective posts.
In my mind, a soft cap is what results from diminishing returns.
Such as you cannot reach a true 100% dodge chance. You may reach an infinite percentage (99.9999999% continuous) that essentially becomes or is rounded up to 100%, but never a complete 100%. That is the soft cap.
This is opposed to a hard cap, such as the 40% hard cap on cooldown reduction or the 2.5 hard cap on attack speed.
From what I understand, you believe the soft cap to be the point at which diminishing returns begin (i.e. 415 for movement speed). And it's true, in this way, diminishing returns does not necessitate a soft cap, but a soft cap necessitates diminishing returns.
