Ooops - apologies - this referred to another algorithm I investigated, and
makes no sense in the context of this algorithm.

Still I believe a blame algorithm would recover a lot of lost data. It
would require a shift register 1,200 wide - with each slot representing the
value during a 100ms interval from achosen edge.
