I used the search function and I couldn't readily locate this question before.

I use P1 pedals and recently purchased a one month membership to Zwift. I've been using TrainerRoad for around a year, but wanted to give Zwift a go since I've heard so much about it. How are those of you using P1s, a dumb trainer, and Zwift calibrating your pedals? Within TrainerRoad, I calibrate prior to every ride, but I submitted a ticket to Zwift and it appears I can't do this within their app.
