Strange old worlds for fun and profit...

Quick and Dirty Starships and Aliens, with d% because I have access to a stopwatch function on the cell which gives me a count in hundredths of a second. I need to let it run and stop, run and stop...

2.77 is 77, then run it again... 3.62 is 62, 6.13 is 13, 8.55 is 55 and so on.
