Yes, please do so. We are really interested.

Note: I doubt that double prec. floating point ops are faster than 
single prec. (according to your slides).
Moreover, I'd like to see speed comparisons related to matrix sizes on 
some logarithmic scale in order to compare the quite relevant gains for 
small sized vectors.

Best wishes,
