Hi,
because of the differences between individual power sources, I actually swap the pedals around. I use Garmin Rally pedals on my bike outdoors, and for indoor riding I have an Elite Direto XRT with a Zwift Ride, where I then move the pedal over. Around spring, I ran into exactly this problem, see this discussion, where my indoor workouts started to feel quite hard after I began riding outside and mixing power data from different sources. Unfortunately, before I realized what was going on, I ended up overtraining quite a bit, which led to several issues that put me out of training for almost two months.
When doing any conversion, you also need to be careful because it behaves differently in steady-state efforts versus short intervals, where the difference may not be as noticeable. From other discussions, I’ve also noticed that the most commonly recommended approach is to keep using the same power source all the time.
