What's the BEST Tire Pressure in Snow? 10 to 50 PSI Scientifically Tested

In theory a high tire pressure puts more pressure through a smaller footprint to increase grip. Also, in theory, a low tire pressure puts more rubber in contact with the surface of the road to... give more grip!

Both can't be correct (well I guess they can as tire testing can be very confusing) so I'm going to scientifically test low tire pressure vs high tire pressure in snow traction, snow braking, snow handling, ice traction and ice braking at 10, 20, 30, 40 and 50psi to finally answer what pressure is best in the snow, low or high tire pressure.
