Not wanting to add further confusion, but I imagine the calculation of Handicap Index will be further complicated by having a mix of rounds played off different tee's in a players best 8 from 20 and therefore different course ratings?
It does not matter adjustments will be made against the course rating which will normally be (as you say ) different between tees and a players Course handicap will often be different between the tees. Adjustments will be made by comparing the Coures Rating as modified by the paying condition calculation against the players net differential.
Even under CONGU UHS, which uses the course CSS, which will often be different between tees.
