I’m far from the A-cat MAP values when looking at Intervals (Morton 3p models) thats why I suspected that the AND is not implemented. Someone with match skills pls correct me.
Harsh question…
We don’t make allowances for super heavy people or Tall people, why do allowances need to be made for super light people?

My thought process was wrong then 
No please no. There are already an option for that.

Worth a check though, it must all be VO2 triggered then
Terminology thing. I think someone did a glossary…
For me:
Categories - global groupings of riders with fixed boundaries - you can be promoted through them. Such as ZP A,B,C,D, or real life Cat 5, cat 4 etc etc.
Pens - how riders are organised for a race. Can be different race to race.
I don’t think there is a need, long term, for categories on Zwift. Instead, let race organisers determine how fields are split for their particular races, and manage progression through a global ranking system.
But this is not for this thread, it’s for the other big one.

I dont get how a bunch of Cat C’s beat me in a race today (I bounce between ZP Cat C and B) and yet on ZP paper, I should have beat them. Fact is that ZP numbers dont tell the whole story and the course suited those who had stronger numbers in, dare I say it, the key areas of the power curve that ZP Cat doesnt care about which also happen to be a race weakness for me.
I am fairly sure that those Cat C’s that beat me tonight would be Cat B in the new world (but would still have still beaten me, which is more tolerable than them being labelled C’s). Doesn’t change the fact that being at the bottom of a Cat is possibly going to have less competition than when we are in the front group or two of the Cat below. I’m already ready for Results based Ranking system though … lets go!

As intended these new cat boundaries will move a lot of people up (none will be moved down I assume). This would imply a smaller d-field at least, and maybe also smaller c-field, and more people in the A-pens. With reference to the zwiftinsider article showing that the B-population were the by far largest when combined with the amount of races they do. Would be interesting if @xflintx could reveal some statistics on how the different fields (or rather populations) will change based on the new boundaries and what the performance gaps are in the different categories.
As mentioned by others these changes will probably lead to different race dynamics in the D, C and B pens. But perhaps not in the A-pens? The only change here is that there will be more, and maybe also weaker riders moving up. Maybe these changes combined with the racing population demographics should lead to putting the A+ into its own pens? There is probably quite a large performance gap in A I guess.

and my main hope is that while the pool of D racers right now will be smaller as some get moved to C it will encourage more non-racing D to start racing without all the sandbaggers.

The bigger change here is no sandbaggers to ruin a race. The rest is shuffling the goalposts a little to accommodate theoretically fairer racing, which in itself will be more attractive to all Zwifters. Win win.

Totally agree, Gordon. I believe that if you categorised them, the vast majority of Zwifters would be C or D (or lower) but they’re put off racing for many reasons.

Ultimately, we should aim for no categories whatsoever: only a single list with every rider’s ranking score. Leave it to organisers how they wish to split the pens.
Result: no promotion/demotion, no cruisers worrying about moving up, no sandbaggers trying to punch down, no borderline cases complaining of always being left behind (as some races will have boundaries where they’ll be the strongest in their pen).
An organiser could, for example, create a race with pens with very narrow boundaries. Five pens spanning what would now be “Cat C” but based on ranking.

@xflintx is there anything that can be built into the model that gives a double category upgrade for anyone who gives a forum comment like this

The old Cat system had so many flaws, and i think almost all of them were discussed in the Anti-sandbagging thread.
One of the biggest problems was that the system was too dumb. People with great 1-2min power, or with great 5-8min power could dominate the events at will, if they choose the right route that played out to their strengths.
People with massive Z5-Z6 Power could dominate at will without being upgraded.
Some power values were crazy for a Cat B race.

I’d also like to see the expansion on number of cats. likes of Mad Monday using split cats works really well but is a bit of a pain having to setup multiple events and try get riders the correct link.
Cats A to Z possible then give the organisers the power and the best events will get the numbers.

You can get a feel for the spread by looking at the signups in Zwift Power. You can also see the people that are categorised B, but are now in A (etc down the categories). Example here: ZwiftPower - Login
You are right, naturally there will be more riders in A, and I hope this will lead an A+ category. The ceiling on cat A is infinite.

Yes, but not for the A-cat, wich is what my qoute was about.
