Why is my App data different than bike display?

Data discrepancy from app to bike display

My apologies but the updated app now calculates independently then the bike display because the app uses a slightly more updated calculation then the bike. The old app would just mirror the data of the bike display. But since the new app only uses the data to calculate its own numbers, it can only use the data while the app is being used. Any disconnection disrupts the collecting of data until it is reconnected.
