Thank you for posting this issue.
We do have very similar situation. For this winter I bought second Kickr Snap just for me to ride with my partner together. I was so excited and sure it will help me to ride more than last winter since ride together is sure more enjoyable.
Opposite is true - after few rides with my partner I better “sit in sofa”. There is the reason - my partner start ride usually earlier than me. In moment I enjoy his ride for first minutes everything ( watts and speed) looks good but after few minutes my power shows numbers I’m never able to hold in real ride and - what is worst- I do not feel I work so hard in that moment. ( up to me - it shows double value and if I stop to pedal - my watts are for several minut around 70.)
On opposite side my partner ( who is much much better) his watts value is in the same moment getting on very low level even he push so hard and he is not able to keep tempo with me!!! so in the end - we do NOT ride together what was reason to buy second KICKER.
We try several set ups, this and that - NOTHING help to solve the problem!!!
Trust me - this unrealistic situation is very, very annoying and really brought me to the question do I really need to use Zwift???
Thank you for any advice and help.
