Default Fuel burn off on Garmin network?

I have a Garmin 7012 with the latest software. Hooked to my N2K network are my 2010 twin Yamaha 115's. The fuel burn information is put on the network via yamaha gateway from the command link hub. When I fill up I set the full tank option on the 7012 and I can watch the level based on the engine burn off. It works fairly well, except now that I've had a few fill ups I notice about a 10% error consistently. For example it will say I burned 50 gallons but I fill up and it only takes 45. It is not a big deal since it is consistent. Is this adjustable? I tried looking through all the menus on the 7012 related to fuel but couldn't come up with anything. Not sure if the unit uses the ground speed based on gps to calculate the burn off or strictly what is coming from each engine's computer. Any help appreciated.

The fuel burn is adjustable on the Yamaha command link gauges. The Garmin is taking a feed from the gauges - the Garmin doesn't calculate the burn.

I have my guages set up with the 10% difference. I guess I use it as a safety net. I am a firm believer that --
The only time you have too much fuel is when you are on fire.
