Thanks for the explanation. So what's the difference between the rule of 12ths
and the rule of thirds. In the rule of thirds the first two hours it goes down 1/4
which is the same as your 3/12th. The second two hours it goes down 1/2 which is the
same as your 6/12th and the third two hours it goes down 1/4 which is the same as
your 3/12th. See I got it right in spite of myself.

Not a lubber, not a lubber, not a lubber... Yippee!

Cheers,
Ellen
