Exacta box?

Its a diff. bet of course.

I think the one thing people forget
is that you have the distinct possibility of
losing twice. You kinda took that into account
with your math.

But it might be better to go with one horse at 8-1
or 10-1, and bet less. That way you do not have the
chance of "losing twice". As much as odds change now
its also dicey to bet dutch. So much late money. I believe
there was another thread on this subject.
