Signal K Node server plugin to compare performance and write best performance to sqlite3, database.
This is now both a backend plugin and a webapp with polar graphing, to be able to visually see current performance compared to previous sailed performance.
If the plugin stops, re-enable it and look for strange strings in the polar tables in the plugin config view.
As this plugin stores polars in a SQLite database structure, in order to delete unused polar tables, use the /plugins/signalk-polar/listPolarTables?uuid= query.
