For anyone who's interested, you can follow the link below to download my current EcoSmart graph.
In order to apply it, you'll want to save and unzip the file. In artificial mode, change your start day time to 11am and start night to 11pm. Then, select the "Import to Selected Graph" button and select the file. Let me know what you think!
