Isn't ZRS, or at least what Zwift are doing, just the old CE system in disguise?
E 0-180 = D riders
D 180-350 = mostly low and mid C riders
C 350-520 = C sandbaggers, low B, mid B
B 520-690 = Upper B and lower A
A 690-100 = remaining A and A+
They could have just seeded everyone using the old CE setup, given all Ds 100, all Cs (excluding the sandbaggers) 200, upper Cs, low Bs, mid Bs 300 etc etc, so new groupings
E = 100
D = 200
C = 300
B = 400
A = 500
Then let results promote/relegate based on results.
Top 10% of a race increase their score - winner 10 points, 2nd 8 points .... not thought the scoring out exactly but wouldn't take long to come up with something reasonable.
Bottom 10% in a race get a minus score equivalent
Middle 80% of riders no score change
If a D reaches 250 points, they are promoted and their score changes to 300 points (stops the yo-yoing each race)
If a D is relegated they set the score to 100
Races with less than 10 riders, no impact on scores
If riders DNF 3 times in any given 3 month period they are penalised with 10 points
Minimum effort could be as they plan, anyone doing it has zero score change (or 5 added to their score)
No degradation of scores, so if a rider with a new C score of 320 goes off for 6 months, they come back to the same score.
Needs more thought, probably enough holes in it to make a good dutch cheese, but works similar to the old CE but should control sandbagging more. Most riders coming mid table stay where they are, which seems logical.
I bet they could have done something similar to this in no time at all - would have met 90% of the racer's needs, would have answered the sandbagging problem that some didn't like in the old system and after the initial groupings, removed power from the methodology and makes it purely results based.
Right, I'm off for lunch whilst you guys rip my logic apart
