Is anyone using a service where you send in your Engine Monitor data and get reports on that data? Something like the Savvy Aviation Analysis? Do you feel like you get valuable info? Feedback or thoughts about it in general?

I belong to an RAA chapter that built a plane with an O-200. After 150hrs of problem free flight in ran very rough one morning, then eventually cleared up. We have a Dynon engine monitor and a Savvy subscription. Sent the data to Savvy and very quickly got the results, saying a stuck exhaust valve. Well worth the $20/month, considering the problem was found without even removing the cowling. And yes, they were right.
