Thanks @xflintx and @gloscherrybomb.
I am back to being a B rider ad expected. I am actually pretty surprised that the system picked up that I am a B not a C almost B as Zp, good job on that.

Correct.

Sadly still a B when really a middling C. It is what it is I guess

Looking at the above category logic, what do you think made you a B?
Canāt seem to get Intervals.icu to show my MAP - says if it doesnāt appear if data not good. Is there a calculator somewhere I can chuck my numbers in?
Not sure, with a CP of 224 and CP 3.06 w/kg must be the VO2 I guess, will have a look in detail tomorrow as have not fully read or understood the above to assess it with a fair crack

Yeah my son is the same - 40kg - 3.4w/kg but FTP of 144 categorised as a B. He is a D in zwiftpower but c feels correct. Id 469161

Thanks @gloscherrybomb and @xflintx - well communicated now, even though some of the maths is challenging my brain (thanks to Intervals however!)
Coincidently in the past 48 hours, Iāve gone from ZP B to C almost B, and back to ZP B - Intervals has me at 251w CP and my MAP is 3.87w/kg (and Cat B in the test events). So looks as though I will continue to flip/flop between B and C as I have done for ever (excl tweaks). Looks to be fair enough to me (bugga).

Excellemt chaps , back in the game then . Rules laid down so we know what they are ā¦
Pen enforcement feature works (easy enough to test and verify ) . I trust on that basis it can therefore be immediately rolled out for ALL events after the trial .
Categorisation measuring no doubt will continue to debate but 99% of us are not going to see a different category from that issued by Zwiftpower .
Question ; Will these new metrcs and resulting categorisations be proted over to Zwiftpower in the short/medium term ā¦ to unify the platform on this .

MAP is a trickier one. I think the best way is to look at the 3P CP model, and then the (modelled) values for 5m-8m power. Roughly the average of this will be your MAP as far as I can tell.

My lightweight wife appears to be in the same boat. Sub-200 watts but bumped to B.
Iām a definite C on ZP so not sure why Iām a B now, but in fairness I was cautious about losing more weight due to my wkg last year being in the B cat briefly which was painful racing for a while. That being said, where I enter a race with C riders only rather than mass starts I can nearly always stay with the front pack up until the sprint. If there are 10 riders in thatc front pack from a start list of 50, Iāll finish 9th or 10th overall. Rarely happens any differently. Maybe if Iām B Iāll have to up my game and train a damn sight harder and maybe it will do me good as it is pretty dull finishing last of the front pack come what may. (If it is a mass start I can wheel suck like a pro at times and provided very few Cs managed to grab the B group I can occasionally get a medal)

Brilliant work @gloscherrybomb & @xflintx this is good to see community and Zwift coming together to improve things in the right direction. Liking it

Iāve been able to use data from my power curve in ZwiftPower (which doesnāt include solo rides, so is admittedly incomplete* versus this new system) within the HighNorth spreadsheet to calculate my Critical Power with 99% āgoodness of fitā and understand how/why Iām now in cat C in these events, matching my current ZP category. My 5-8min power is pretty much a flat line 
, so thatās similarly easy to work out against the MAP/VO2 boundary and understand why Iām not tipped into B that way. It would be good if the calculations incorporated workouts too, since that would make Zwift truly pointless for deliberate sandbaggers/cruisers.
*It does cover 90 days though, and I mostly take part in events so I consider it to be pretty close.

@gloscherrybomb @xflintx
I know you said feedback elsewhere and this was for questions, but everyone else did so here it is.
In summary: Brilliant from the 2 of you. I had a bit of a rant earlier and this nails everything (well, assuming race ranking is out the window for now of course).
Just shows what can be done.
@xflintx - Especially well done as you are the one from Zwift with your head in the firing line and have taken it like a champ and more importantly listened. I hope youāre aware that the thousands of posts are all because so many people are massively invested in this and want it to be right. I just texted Eric. He said take the day off and put your feet upā¦ you deserve it. Tomorrowā¦ race ranking maybe?

What about hardware restriction first?

The update to the rankings keeps me in B - no change, but I wasnāt really expecting one. So from that perspective it looks fine to me.
Itās great to see the turn-around on the feedback, hopefully a bunch of pitchfork orders have been cancelled

Just remember that I said we were building flexible and scalable systems, with category enforcement being just the start. Letās get through the tests here and get category enforcement as a permanent feature then weāll come back to that bit above.
Mostly just want to convey that these tests arenāt the end. Theyāre really just the beginning.

Love it, a smart trainer being smart enough to detect a weight doper
