Tips for accuracy - Speed

Hi - I’ve entered as much real world accurate info and I’m still finding speeds are higher than actual by about 10-20%. Is there a correction factor or other means of adjusting? An idea may be able to upload a segment with elev, speed, power, etc to adjust for real world conditions.

Thanks
Mike

Zwift calculates speed based on several different factors, one of them being in game physics. So your speed won’t necessarily match real world speed. As long as your speed is proportionate to the amount of Watts your trainer is feeding to Zwift it should be fine. I do like the suggestion!
