Analogue fuel gauge calibration spreadsheet

[Canuck]

I've started a spreadsheet to get a rough idea of the calibration of my two fuel gauges. After every flight, I'm dipping the tanks to see how much fuel is left, and comparing it to what the gauges say. I'd never rely on this when my watch tells me I'm low on fuel, but I still like to have a rough idea how to interpret the readings. I have enough points in the scatterplot now that a trendline is starting to emerge (lots more needed):

If anyone's interested (and has a calibrated dipstick), feel free to make a copy for your own plane.
