Because he raced badly? And it wasn’t cat enforced?

Yes this is correct. I meant short duration power >2m. I have already explained in posts above why you cannot do the same with even shorter durations.

here’s the alternative solution

I think the real purpose is to divide the categories so that each participant can expect the same winning percentage. So I feel that the method of determining this category is a little different from its purpose. CP? FTP? I don’t know what that means on Zwift. But I know I can stay in the first group until the end and the rider with the best sprint will probably win.
If riders who have little hope of winning are promoted, the decision is wrong. The category determination method needs to be updated.
No that is not the goal. The goal is to divide the race into 4 groups so that there is winners at different levels.

The system works! /s
What exactly does level mean?
I think it means the same level of Zwift racing ability.
If not, why did Zwift adopt a fitness level-based category instead of the simpler results-based category? Why is there so much discussion about sandbaggers, cruisers and categories?
Of course, it may not be possible in the 4-5 category, but if each participant has the same level of Zwift racing ability, you can expect the same winning percentage. If there is a big time difference between the top and bottom, I don’t think this is the same level.
Come on now.
That is not the purpose nor should it be. The only way to achieve that would be to have the number of pens = the number of participants.

Posted this on the other thread but valid here too as same typical discussion points.
We have you with an estimated CP of 250w as of 5th May (it was 252 previously). This is 3.125w/kg.

You should play with some numbers in the HighNorth Critical Power calculator spreadsheet. The fact that your 5 minute power is way higher can explain the difference. As an example, having a 20 minute power of 300w and a 5 minute power of 350w then you get a CP of 283w. (the SS needs 3 inputs, I just fudged that a bit…). If I change that 5 minute power to 380w then CP drops to 273w.
That is not really the goal of that spreadsheet, it was made to calculate cp from a set case.
If you truly want to use that you need to expand it si that you can input value for every 10 seconds from 2-60 minutes.
In reality changing the 5 min power has impact from 2 to 10 minutes. If you pull up a curve at one point it drag those around it up as well.
CP is a bit more complicated than just 3 numbers.
I calculated your CP (W’) and i think if you do a 3minute effort of more than 330W you will be back in Cat C…let me know if you can do it and if it worked.
Maybe I’ve got this all wrong, but once you’re upgraded in the CE system, the only way to reverse this currently is to wait until the “offending” activity has expired after 60 days?
I don’t think you can simply down-cat by manipulating your figures with one (or even multiple) below-par effort(s). Surely, it’s not going to be that “easy” to game the system?
Please forgive me Dejan if I’m misinterpreting the context of your post; my head is spinning with all this CE stuff and I could easily have gotten hold of the wrong end of the stick (not for the first time 
).
Yes, I believe you do have to wait the full 60 days from the time of the activity that upgraded in order to have this reversed(unless you have another effort that is above the threshold in that time range).
Maybe a bit counterintuitive, but I think Dejan is actually suggesting doing an above-par performance for 3 minutes only. Something to do with how CP is calculated – shorter duration stronger efforts can seemingly contribute to a lower calculated CP and Cat.
If you are very close to the line, then depending on what triggered the upgrade you may end up going back down with another effort. For example, a strong 20 minute effort may bring you just above the CP line. If you were then to do a massive effort in the 2-5 minute range, it’s possible that would drop you back down below the line. In most cases that won’t be true but certainly possible if you are very close to the line and your short duration power is very strong relative to 20 minute power (also very dependent on your other activities.)
Thanks, this is the bit that I’m struggling to grasp.
Surely any effort that is above your “norm”, demonstrates an improvement in your performance and surely, in isolation, can’t lead to a down-cat?
That really doesn’t make any sense to me; at the very least, it’s counter-intuitive. 
You are correct it doesn’t make sense and that is not how it works.
People are using the 3 value calculator completely wrong and make assumptions. See my post a bit higher up.
