FadeRadialBlur not being gradual

[BonesTheRabbit]

Does anyone know the formula for how the fading speed is calculated? It seems to be related to the intensity. IE: If the intensity is halved, the time it takes to achieve full effect is also halved.

Update: I did some fiddling, and I think that the second value is actually "Number of steps of intensity taken per second." So, hypothetically, if you had an intensity of five, and wanted it to take five seconds to reach that intensity, you would put the second value as 1. I'm not completely certain, though.
