Ah. Gotcha. That was kinda two different thoughts. One based on the request of the OP here, and the other on your question about how to make it embed properly.
I honestly never promised it would be "correct" to real VU ballistics, but I notice you're in RMS mode. I promise it's accurate for that. I'd be interested to see this compared to maybe the Slew mode, though. The way I read the actual VU definition/spec made me think that would be more "realistic", but IDK.
I actually have no use for this plugin at all. Just trying to help.
