Todd,
Some (not-so-serious) Questions from the mathematically uninitiated:
1) Does 'stopping the time' count as a contribution? Isn't there usually
some sort of official timekeeper separate from the team to keep things honest?
2) Does "builders per second" measure time, or does it actually measure a
number of builders? To measure time, wouldn't one need to look at "seconds per
builder", the accumulation of which would give total number of seconds for the
project - the number itself being the average time spent by each person to build
a little while?
3) Were you on the first team, and therefore a little miffed that this
challenge arose? I would be, too, but I might include lunar orbit decay and
quantum variance in my calculations to just button it up a little more.
Please don't take this the wrong way...I just really don't understand your
calculations. Mine would have seen things differently - again, I'm
mathematically uninitiated. Hope you have fun.
Peace and Long Life,
