RC Vol Control

Dear Team ,

I have been using the Single SW slew vol adjustable .

I understand this module is RC optimized.

However I could not find any relationship between the value I set for SW Slew rate and the corresponding time it takes to slew the signal .

I read many posts but my observations do not match with the given post at Sigma 300 slew rates...

Could you please establish a relationship and tell me 

If say I set the SW slew rate in this module as  5,6 or 7 then what is the corresponding time(in ms)  it will take for my signal to reach it's maximum amplitude value of 1.0  from 0 for my 0dB input signal (say).

Please share your feedback
