That would be awesome, only problem would be the lack of CCTV in both of the areas. In the town there's some, but from where I know the camera is it wouldn't got the best view of the postbox. Although, since I've got a few stamps left, and I plan on dropping a few more and filming people's reactions to it over the next few days.
I know the mathematical basis would be good, but that would be effort There had been other aspects like that I would have liked to also test, like distance from postbox, but my tutor for this wanted me to keep it simple. But when I do the filmed ones I'll defiantly time it as well
