flop-count

Dear Group-

Is there a way to compute the flop-count (i.e., number of sums and
products) in matrix algebra ?  For example:

ScalarResult = x.A.B.C.D.E.F.y

where:

x = 1 x ... vector
y = ... x 1 vector
A,B,C,D,E,F = ... x ... matrices

I was considering the possibility of using FullForm, Head, or counting
the number of Plus and Times instances, but no luck.

Any help is appreciated.

Thank you.
