One ambiguity for anyone reading this in future would be... I would hope that both experiments already had worked in the impact of the angle of the board on the gravitational force, and the 6.8 the op turned in was with that taken into account. But without taking into account inertia and friction.
I feel like this is one I'm going to have to try at home.
