Question about using this spreadsheet to fine tune my C5's 4L60E

From what I read, since the VSS is in the rear end of the trans as opposed to the transmission like a Fbody, So when it comes to a gear change, I leave the stock gear number (2.73) in the speedo calibration table and subtract the % of difference in gear from the shiftpoint/tcc lockup tables. I did all that a while back and it seems good. This part I understand.

Since I have a 3.90 rear in my C5, my question is, can i use this spreadsheet dial in my VSS table? Or do I leave all the values (gear ratio, vss pulses) alone in the "general" VSS Table?

Below is an example of the spreadsheet and what table I'm talking about. I pulled from a thread on this site a while back
