I have moved from an Elite Direto to a Wahoo Kickr core,zwift cog and zwift click. I did average 216 watts and about 20kper 30mins, since i got the new kickr core, i can only average about 160 watts and 16.5 k per 30 mins, and thats hard work, read some items on here but cant figure it out. Any ideas?
No one can speak of your setup without comparing: a) the power output measured by your trainer to b) the power output measured by a quality power meter; however, “sadly”, it’s well known that lower end trainers like the Elite “hugely” overestimate power -think about it, the Elite Directo is cheaper than a quality power meter, so how accurate can it be…?!?
As a color note, this is what ChatGPT thinks about it “When it comes to the Elite brand of trainers, there have been some reports and discussions within the cycling community about potential overestimation of power output…”
Note: that’s why Zwift should show/report the device type where the power output is coming from during races… 
Cheers and if thats the case, heehoy, it is what it is, not going as well as I thought I was. Thanks
That is why it would be nice to be able to pair 2 power sources.
One to play the game and the other just shows accuracy of the first source.
It would be good to show that all the time.
That’s old school 2.5w/kg Coco cadence pace-partner speed on Tempus Fugit with 100+ riders in the group before all the pace-dynamics “tweaks” came along. If you were alone then doing 40km in 60min is just a little bit fast.

Exactly on the displaying power source… when you do a rouvy ride they display what trainer someone was using once the event is completed… historically the “leaders” are using 2017 ish era Kickr trainers which are know for being out to lunch, or Elite stuff… lots of people use Tuos or Nero rollers as well to look the hero of the day… you very rarely see anyone on a Neo/Kickr 5+ gen at the top of the board… and the ones that are deserve to be at the top of the board…

Is this a brand new Kickr Core trainer? Is your firmware on the Core current… the Core is accurate to 2% and even if the Direto was only accurate to 2.5 or 3 percent, 56 watts is a HUGE discrepancy… earlier this year, Wahoo added firmware to the Core that you don’t need to calibrate the trainer, and brought it inline with the Kickr 5+ models… So first thing Id possibly do is a spindown calibration if its possible pending firmware version… outside of that,its hard to know whats actually accurate without another valid power source to compare against…
If Zwift would allow a second power source to be displayed, all the bad trainers and sticky watts would be exposed
It would not people from taking advantage of those issues but it would expose them.
Event organizers could restrict events to dual recording only.
They already do this with Z Power.
They are exposed and some events are restricted but people may still ride and train and participate in other events.
