YEp, knew about the divisible by four part, just hadn't
played with that in the code that runs Feb 1 yet.  Would
like to see that other formula when you find it.  I'm sure
we could plug it in.  TImo's batch calculator does some
interesting things.

Think I'd heard of the other one too, but was thinking about the divisible by
4 bit, just hadn't implemented that one
.
