Hey Pappy !

The pinion offset (or 3rd member offset) does not play a calculation in the determination of top link offset. The track width & friction (or power loss) from the specifics of the rear end are used to calculate the optimum top link offset.

While I don't share my formula, I will say the more power loss a specific rear end creates, the more it is unevenly loading the left rear tire & the more we're going to move top link to the passenger side to neutralize this.

For folks that don't know this, all symmetrical rear suspensions experience "torque steer" ... meaning the left rear tire gets loaded more than the right rear tire. The amount (or degree) is directly related to how much friction a given rear end has, from it's hub bearings, carrier & pinion bearings & R&P gear teeth meshing.
