Strava shows inaccurate power data
I've noticed issues related to power measuring/output/estimations.
It appears that for some reason when using a power meter (Garmin Vector/Edge1000) Strava appears to "downgrade" the ride by approximately 15% (both average power and NP), yet when using the Strava iOS app the power ESTIMATE as compared to an actual power meter is about 15-20% MORE than what the power meter is demonstrating. I can see 1-3% differences, but these are huge. I've taken to not relying on Strava for much of anything except for cataloging my rides.
How in the world can anyone even trust the Strava data? The only thing that appears to be accurate is timing and distance. Even then I've seen minor discrepancies.
Why is this occurring? Anyone with similar issues? I've got a "ticket" in the queue, but two weeks out and I've yet to hear anything back.
I've taken to using Garmin Connect since the data is consistent with what the Edge 1000 is reporting. At least I can gauge my performance with some consistency.
