Kickr Bike Shift

Today i did a FTP test on Zwift with my Shift….
It was 50 Watts below my Outdoor FTP.

I am completly empty after the indoor test…
Result 219 instead of 270 some weeks ago.

It‘s crazy how bad the shift is or how off the watts are wrong…

My Companipn App shows orher Watts than on my MacBook during the ride.

It‘s crazy & i don‘t have words for it
