How fair is a fair coin flip? – Contribute to a scientific experiment

Have you ever tossed a coin to settle a bet and wondered which side to choose? Diaconis (https://doi.org/10.1137/S0036144504446436) proposed model predicting ~1% bias in favor of the starting side up.

We are a bunch of researchers coin tossing from 9am to 9pm CET today. Yes, this is a ridiculous project but what is life about when you don't do something stupid from time to time?
