How accurate is Zwift zPower
How accurate is Zwift zPower really? Is it anywhere near what a real power meter can do? Is Zwift zPower even close enough to train with? Is my Zwift FTP accurate?
Zwift has spent a lot of time working on a way to include more cyclists, even those that don’t have access to expensive power meters. I was one of those people! All the time I was on Zwift I was curious to know if the numbers that I was seeing on the screen were anywhere near accurate… I was hesitant to share those numbers since I felt like they could be inflated, and as soon as I got onto the road in a real ride or race, I would be obliterated! That’s why I needed to test the Zwift zPower accuracy :)
If you do want to start training with power, and want to get that edge in your training game, checkout the power meter I just bought for myself (the 4iiii Precision) here: https://amzn.to/2YsGb8K
This test was very helpful for me personally to see what the accuracy really looks like. I was very impressed! I know a lot of testing and calculations went into this, but even with that I will say I was very pleasantly surprised by the accuracy over the course of the test. The only differences (as you can see in the below link) were when power quickly ramps up, and drops off. The main reason for this (based on my educated guess) would be that power meters are able to read instant changes in torque applied to the pedals, whereas the calculated Zwift zPower is only accurate based on the speed of the bike against the resistance of your specific trainer. Even though the power can instantly increase, your speed needs time to ramp up (acceleration). That is what accounts for the lag in the power readings, which I noticed to be between 3-4 seconds usually, unless the sprint was especially sudden. The more gradual the changes, the more accurate Zwift zPower becomes comparative to the actual power meter.
If you want to see the specific graph and dive deeper into the numbers, here is the dataset that I used! (My personal power data): https://zwiftpower.com/analysis.php?s...
