Tis sounds like a rip off...
Pretty sure this concept was first thought up by Douglas Adams... 'bistromathics'
From HGTTG:
"Bistromathics itself is simply a revolutionary new way of understanding the behavior of numbers. Just as Einstein observed that space was not an absolute but depended on the observer's movement in space, and that time was not an absolute, but depended on the observer's movement in time, so it is now realized that numbers are not absolute, but depend on the observer's movement in restaurants."
