I haven't touched it. Looks like you added it in 2009. I think we had a mailing list thread on it around that time. Counting flops with hardware counters is really error-prone on current hardware. I don't think we should ever trust it for linear algebra. It would perhaps be handy for people implementing their physics and discretizations, but the numbers may vary widely based on compiler/flag choices.
