The table posted above for Scorchers players is not a 'true' reflection of where they sit after their 1st of a DGR as the calculations are based on the standard 3-Rd rolling method which would be correct outside of a DGR. The reason being is that the site only do the ONE pricing & BE calculations at the END of a particular round, regardless of whether a player plays 1 or 2 games. As such, players on a DGR only get the ONE price increase and NOT the customary 2 if they were to play those 2 games during a SGR. It's one of the vagary in the way they treat and calculate player's pricing & BE during a DGR. It took me a few years to finally crack their code, whether I agree with that approach is another debate.
To provide some examples using the 3 Scorchers players you've mentioned and what their projected prices & BEs will be post their 2nd game scores.
