What is the difference between ERC[Add] & ERC[DeltaAdd]?

Basis

Title pretty much says it all.
Thanks in advance for any info you can pass along.

Quoting from the DS3 scripting docs:

    ERCDeltaAdd: f(v) = v + (c * m) + a
    ERCAdd: f(v) = v + c + a

Where:

    v is the current (keyed) value of the property with the ERC Link
    c is the current (final) value of the property that the ERC Link is driven by
    m is an optional scalar multiplier
    a is an optional offset (additive) value.

so the main difference is that you can multiply the controller's value in DeltaAdd but not in plain Add.

Thanks. That's something to think about.
