I don’t think CP and MAP needs to be on ZP it has nothing to do with ZP. But I think it needs to be on the user profile either the Companion app or Zwift game.
But showing CP and MAP will invite the “sandbaggers” to change weight until they are in the desired category again. There goes fair racing again. 
Sorry if I gave you the wrong impression. There has been work done on scoring/results based, but not all work is developer work.
It’s not going to be very straightforward for them though. How would you know how much the model will change if you go pretty hard on that 3min hill or the other 8min climb assuming you’ve increased your weight by 1.5 kg? you might need to have more details about their parameter estimation and remember where in your power curve your previous best efforts were.
It’s certainly possible, but I don’t think the majority of sandbaggers will do it as easily as surfing the max 20 min W/kg limit 
The key question here is which is it simpler or faster to display in. If that’s ZP, then fair enough.
But yes, it should be readily discoverable by players.
We have had the statement, people changing their weight to stay in Cat will be banned for 3 months, let’s not be unfair and wait to see this happen.
Come on now Gerrie, be supportive.
This would cause even more confusion and complaining than there already is. If CE is the near future, then it needs to outright replace ZP as a metric. That is, the ZP site should should be completely converted to reflect rider CE data, CE race categorization, etc…
The Zwift,com and CA profile has nothing but name, country, gender, height, weight and birthdate. Seems odd to to start adding power data there. The in-game profile data is the same. If you put the info on the screen that’s visible when hitting the ‘MENU’ button while in-game, you’re stuck with the annoying situation that you have to start a ride first in order to see your stats.
Zwiftpower is about… wait for it… power in Zwift. Just add another column to the ZP profile page, stick it inbetween the NP and 20 minute columns. In the top profile area, put CP: XXX under the FTP: YYY number. You still need though VO2 as well though, right?
This I completely agree with. But I doubt it will happen at least not quickly. I don’t think ZP is easy to change since Zwift don’t have the people that created it.
As a quick option it will be best to just display it in the app.
It’s just phpBB isn’t it? I’ve modded and created extensions to phpBB, vBulletin and XenForo in the past (all PHP-based forums), and they were all pretty simple to work with.
I don’t think it would be in any way tricky for any competent developer to work with ZP, especially if they’re already C-style curly brace language devs.
They could find him if they wanted to since he still uses zwift. I ran into him ingame maybe less than 1 month ago
James, I am a bit late on this thread as I have only just been impacted by the category enforcement rules. I am now restricted to Cat A although in reality I am a B rider albeit close to the FTP wkg limit. I have been looking at the High North Performance spreadsheet. It is interesting to note that if there is little difference between the 3 min and 5 min power data the CP metric is higher than if the difference between these two is greater. I recently did a shortish TT providing my highest power numbers across these durations: my 3min was 337, 5 min was 335 and 12 min 320. On the Three test solution this gives a CP 316.9 although the Fit is only 81%. If the 3 min is artificially boosted to 360 the CP falls to 305.3 and FIT increases to 99%. Actually, this is much closer to the average power I held over the 17 min effort. The same impact can be seen on the Four Test Solution. Hence it seems possible that there are likely to be some rogue results if for any reason there is not a spread of power between the durations. I wonder if Zwift are aware of this?
Your 3min and 5min power are roughly equal here. If you really did a full out 5min effort, you probably wouldn’t have to artificially boost the value. The model is the model, it eats what you feed it. Perhaps go do an all out 3min effort and/or 5min effort. Those values are sure to change.
Lin, thanks for your comments. I have two main points; first the shape of the power curve may be different for different rides. For example a TT person may have a flatter curve than a crit racer. As such these two types may have the same 5, 12 and 20 minute power but the crit racer has a high 3 min power. This will lower the crit racers CP metric relative to the TT racer. This may mean that the crit racer is in a lower category due to the shape of the power profile! Second a more general comment it would be preferable if Zwift would articulate the changes it is making, how it calculates the data and where that data can be found, rather than just finding out prior to race your category has changed! Thanks
I totally get what you’re saying about different curves for diff kinds of riders. But the model is based on max efforts regardless of your phenotype. Since you mentioned doing a TT, I suggested you go do a max 5min effort which I can almost guarantee will be more than the 5min PR you set during your ~17min TT.
As for how Zwift calculates the data/category for CE, it’s buried in the 1452 comments above. While you can’t see the exact formula or numbers at this point, the methodology is explained.
Having read large chunks of this thread a number of times and still not fully grasping it…
There’s lots of talk about CP using data from the 2-50 min range; but on the assumption we will be displaying a single data item on a user profile - I assume like on intervals.icu it would use an average value? So would you only be excluded from a cat if that average was above the thresholds as per post 1? Or if any data point is over?
Like many others I’m trying to work out what tips me over the cat; whilst those destroying me week in, week out on every possible type of race continue to game the system somehow.
Also; what do these 2 lines represent??
probably the number they will display is your CP, but in reality it’s your W’, which i’m almost certain by now is weighted heavily towards 2-3min power, that defines your cat
essentially, you’re being shafted because you are a time triallist and not a track cyclist. but you were probably being shafted before CE too
edit: to be clear, having a large W’ essentially lowers your CP value and widens the threshold range, because if you have good short power, it’s assumed you spend the majority of your time training short power. which is fine as a training metric, but kind of stupid as a categorisation metric because you can spend not a lot of time on threshold work and still be at the top of a category in zwift
I was ok as a B - my wins were few and far between. But I could generally stick with front packs (aside from a few ZRL races that are stacked with some Bs with frankly ridiculous performances).
But I get a good race experience which is what I (and I assume many) want.
W’ as in these; or something else (this is another rabbit hole of info to go and understand!)
honestly brother, i only have a working knowledge of CP myself. I didn’t know what it was at all until CE was introduced. someone with more knowledge than me might come along later and be able to explain in finer detail
Read the presentation posted in the OP.
That is the “MAP graph” which isn’r related to the CP W’ theory afaik. You have to change the graph to either Watts or Watts/kg in the options drop down on the power page. Intervals have a great forum, where “all” is explained
