It was my once-a-month office day today, followed by a pub with colleagues. So no riding sadly. Thinking about doing something on Friday, maybe. Possibly a go at the Alpe?

It will be mostly your lack of time away from the temple of Zwift
Partly ... but definitely fixing the chain etc has made a difference as the numbers now are similar to the pedals
Within 60 days I'll be very firmly back in C now the fairy dust has gone 🤣

On my Elite Direto I got higher numbers leading up to the belt snapping.
If one put a longer chain on a bike, will one get higher watts from a KICKR? Asking for a friend!

Going to work my way through the Zwift Spring Training workouts, then try hitting a B race...

I have a Direto. I'll watch out for that
. I keep a spare belt in stock to prevent the existing one from snapping 
You know it.
When did that happen? I presume it's a consequence of the new power ratings

I upped my weight by 2kg, but my stats are also showing that my zFTP had dropped to 296W, when it was recently 314W. Not sure on what basis it’s dropped - my 95% 20 min power in the past 60 days is still 305W. My actual sustainable power atm is probably much less because I’m taking things gently while I get over my cold symptoms…

Your zFTP is actually your CP and often bears very little resemblance to your 95%/20min power.
Zwift don't say what data points they use for your zFTP CP curve calculation, but they do show you some key values on your profile.
My current zFTP is 213.
My highest recent 20-minute power is 230 (ZRL hill repeats on the Sgurr)
My highest recent 40-minute power (new record on Tuesday is 218 - DRS 16 laps of Crit City)
Zwift say their aim for zFTP is to work out your sustainable power "for a long time e.g. >40 minutes"
So you can see mine isn't a million miles away from that goal. But "without fatigue"? MY ARSE!
(Maybe that's the 5W difference?
)

Held on to the slowest B rob-pacer (3.2 w/kg on tick-tock) for 27 minutes tonight before I blew up ... then found the D (2.3 w/kg) group and just about hung on for another 20 minutes
The bike fix has definitely adjusted my power down by at least 10% .... don't even have the legs at the moment to sprint, but I'm pretty sure I'll struggle to get over 700 watts at the moment
At least I won't need to find a new B team to ride for come September
