Determining voltage "locations" on the VC-25/MAF c

[Fast VW]

I have a VC-25/MAF contoller that I am trying to determine where cerain voltages are on the dial. For instance the full dial has the following marks:

1v @ the 7 o'clock position
1.3v @ the 10 o'clock position
2v @ the 2 o'clock position
5v @ the 5 o'clock position

So where is 4.75v? I am currently assuming that 3.5v is @ the 3 o'clock position (halfway between the 2v and 5v marks). That would mean that 4.25v is @ the 4 o'clock position. Am I reading this dial correctly or not? I know that my MAF max voltage read is 4.7v so I wanted to determine where 4.75v was on the dial.

Thanks for any help!

You've got it figured out right - just a bit before the 5V mark, obviously.
