There’s no doubt it could be twiddled and tweaked.
I don’t think the aim is to tweak and improve Zwift Power or category enforcement though. The aim is to replace them with a results-based points system, possibly starting with CS - a bit like what’s going on over at zwiftracing.app
Yep, all depends how long the piece of string is, to change to the proposed race result system, incorporating Compound Score.
Apply a Watts multiplier and the same “problem” exists in many C races. As Alex has said, the ultimate aim is to move towards a results-based system. It would be nice to see some changes in the interim (if Zwift’s new points ranking is going to take eons to implement).
Personally, I like what TFC have done recently with their Mad Monday split-cat series. They have shifted their cat boundaries slightly, so that riders who were previously dominating, for example, “low” C have now been moved to “high” C (the high C’s have been shifted to low B) and the high D s promoted to low C etc.
It gives different riders a chance at being more competitive and minimises the possibility of sandbagging based on the previous series’ cat boundaries.
Sure, but then 3 months from now, someone will post something along the lines of “a quick scan through the top… reveals that X number the have a Y-minute racing best of 240W for 6 minutes…” and so on.
I think it’s probably close to as good as the present system is going to get.
Yeah, maybe a tweak or two but I wouldn’t bother with expecting major changes until we work out results.
I think pen enforcement and using the CP curve are huge improvements.
Using the CP curve gets our attention away from a single focus of 20 min power.
Now, I would like to see Zwift teach us how to take the info from the CP curve to improve the training experience.
Meanwhile everyone is waiting for Zwift to move to Results based racing…we already have that at https://www.zwiftracing.app/
Organizers have the option of PEN Enforcement with AUTO Pen allocation or Manual if you want to have more control of riders entering your events.
I discovered now that each profile page in Zwiftpower seems to list “Zwift Category Enforcement” below “Zwiftpower Category” and explain very briefly the difference.
The CE item is not populated but rather a link to the Zwift feed, but I guess/hope they will fill it in…
Thanks for pointing that out; hadn’t noticed it 
Yes, that would be ideal. ZP cat “above” and CE cat “below” on the ZP profile page (retaining the CE link to explain how it was derived).
Agreed. It would be ideal, but it might be a GDPR-type personal data protection issue since permission hasn’t been sought from the users explicitly to share this data. (Not sure. Silly if it is, but it might be.)
I don’t think so.
“For technical reasons, we have no plans to put this information in ZwiftPower or to make ZwiftPower use the same calculations to determine category, and this is unlikely to change.”

Apologies if this has been covered, but I had let my 9 year old daughter test ride one day over 2 months ago and Zwift[dot]com still appears to be using her weight when factoring my CE. I’ve contacted support and awaiting a reply after it was escalated, but no luck so far. Has anyone seen or heard of Zwift[dot]com using old weight in CE with current efforts? I get the issue with her weight, but the below is showing correct watts from more recently and still using her old weight with no line of sight for if/when it will be updated. @xflintx any guidance you can offer?
Thanks in advance!

It’s not over two months, it’s less than two months (unless they are both February). 56 days. The 11/22 data should go away after 60 days so you won’t have to wait much longer!
Join the club, I’m in my 40s and try to keep fit.
I really cat C and really crap of racing in Zwift.
Infact so crap, I have put out high numbers to keep up been in category C group and I have put in high numbers to place 6th place and the I get ZP in Zwift power site.
3.58 W/kg for 42 minutes - and you want racing C cat? 
Maybe the lack of a power meter is the issue in this instance?
In this instance yes, he got ZP.
But the power reported to Zwift determines his speed!
The story started here:
He is B (Zwiftpower):
FTP 354 (estimated) ~75.2kg
Well one of those three data points is wrong 
Yes, 354 W / 75.2 kg = 4,71 W/kg is wrong.
But he is zwiftpower B, with 245watts /3.26wkg.
It is bottom B, I know - I have been bottom C for 3 seasons, so I can understand how it feels.
The category boundaries are here and should be respected.
Edit - I don’t understand what Matthew’s problem is - he was racing B in 2022!?!
It was Category enforced event and before the event I was in Category C otherwise I could not enter the event in Category C, like I couldn’t not enter Category D at the time before the event.
When you’re DQ-ed with the code “ZP” it means you were riding with zPower (Zwift’s calculation of power based on speed and cadence) which means you did not have any power measurement. In some series that’s allowed, in some series it isn’t (because it’s usually very inaccurate). So it’s not about which category you chose.
