Hi @Coach_Theia - it is definitely changing on Zwift racing!.
Here is a link to the new Category Enforcement infrastucture : https://support.zwift.com/en_us/category-enforcement-faq-rJ5CQrpvc
There is good news, it’s not FTP related but takes into account the whole power curve. I am not an expert on it, but the new brackets are captured in the summary above. Every ride on Zwift is considered for the last 60 days. It calculates your minimum category from your maximum efforts in the last 60 days.
We learned this is the databased Zwift it using to calculate our efforts: https://intervals.icu/ It’s a great database and has a ton of performance data - if you like data!
Lastly, I have no idea why ZP has lost your data? Any chance it’s a glitch? When was the last time you raced? Maybe look at the new database? Open a ticket?
Yes, all signs point to ZRL using category enforcement. We will wait and see, but it looks highly likely as the way of the future.
Hope this helps.
