It’s worth bearing in mind that whatever system you use and upgrade mid-series, the outcome would have been the same. This used to happen just as often as when we used Zwiftpower for category structure.
It’s likely that your Crit City effort (and bear in mind the calculation is done on a 2-50 minute power curve estimation) is to be the cause of your upgrade.
re: category split problem under Zwiftpower, that’s understandable; it doesn’t seem like an easy problem to solve.
re: Crit City, that race was more than 2 months ago, so shouldn’t have mattered?
Il mention before someone else does…
Cat B race won with a 5.2wkg 20min effort and 4.9wkg effort for the entire race (40mins).
Rider is still a legit cat B…
Still no intentions to look at this as it’s fair racing?
if it took them 40 mins to do the innsbruck short course (i am assuming you’re talking about zrl stuff since it’s zrl day) then that is basically bang on for a top B time so pretty much, yeah. the top 4 Bs in my D1 split went under 40 mins and were all over 75kg
4.9wkg for 39mins is slightly out of B cat metrics, when others get bumped for being .1 or .2 over the threshold.
Tbf she won it solo, as dropped everyone and won by over 90 seconds - had a group kept up with her I presume she would have been quicker due to the draft.
to be honest i just looked a little closer at the emea north B1 numbers and like the entire top 20 went over 4.3 for 20 and are now A. well, the old 3x95% of 20 system has huge holes in it anyway. in one of my recons i rode the climb at 19:50 pace and the five people who stayed with me got WKG dq’ed even though i was like 15w short of the cat limit
ZRL isn’t cat enforced? Or am I missing something…
I got code 7!
I always give everything I have, and this time I stepped outside of category B…
I got at the same time : my best ftp ever, my best 20 minutes ever with 0.8w over the 250w limit for B (so code 7), promoted to almost A and probably to A in category enforcement (I have now 257w cp)!
And I am happy… in 2018 my ftp was 180w, 2019 210w, 2020 220w, 2021 235w, 2022 255w
And my 1 and 4 minutes power are my best ever.
So you know what : i am happy!
No it isn’t
Innsbruck KOM twice in 2 weeks was what put me to A in the old system a couple of years back. That’s one of it’s biggest flaws - it took a race like that force an appropriate upgrade effort, especially if you were a reasonably efficient drafter on other courses.
I’d imagine the vast majority of B1 racers are already cat A for CE events. Shame we can’t see that somewhere (yet).
Same rider was mentioned in here a few weeks back… (it was one of the cat enforcement threads, there’s about 7 of them now so might not have been this specific one)
But, yes zwifts primary race event for the community doesn’t have cat enforcement…
14 posts were merged into an existing topic: Category Enforcement Trial - Next Steps [February 2022]
So at the moment we have:
All co-existing and competing with one another in multiple aspects, all with a different definition and/or importance of ‘FTP’, and all official, i.e. provided by Zwift in one way or another.
We need to bear in mind that the vast majority of people won’t bother reading all these explanations. It’s a complete mess.
This might give the wrong impression, i.e. that WTRL use Autocat in ZRL, which they don’t. WTRL is so much clearly “the best” (in WTRL’s view) that they don’t even use it for by far their biggest competition.
This doesn’t take away from your main point of it all being a mess though.
Ah okay, sorry. That makes it even more confusing. 
It’s still a thing though, and WTRL as an entity is still ‘Zwift’ through the huge amount of influence and power they’ve been given as part of the ZRL arrangement (which I’ve moaned about), so it’s an easy mistake to make.
We need to stop referring to the Zwift Race League as WTRL. It is Zwift HQ primary community race, it is run by WTRL for Zwift. Zwift HQ choose the race & schedule, Zwift HQ set the tone for event.
WTRL Chase races, use Cat enforcement
WTRL duathlon league doesnt use any I think.
WTRL have a number of events, the specific issue is with the Zwift Race League.
My point was more that there are multiple possible answers to the general question posed in the thread title. This latest heated discussion over a specific ZRL event merely exposes the problem with all these categorisation systems existing at the same time.
Think what will happen if race organizers get to choose how racers are categorized, using CE and tweaking the limits or using other metrics.
4 category systems is just the start.
Every event should define front and centre how the pens are determined, and there only needs to be three variants.
It should be very easy to know which event type you’re entering - either no barriers, a known enforced barrier, or a set of barriers that you need to read up on. Tons of variants within Custom is fine IMO, that’s the whole point.
I need to go through the list of Events that have Category Enforcement turned on and add it to the event title.
It’s a horrible job and I’ve been putting it off.
