Adding on to the praise, I wanted to also comment -- thanks for doing an analysis of the results. Having implemented it was neat, but the honesty in revealing that what you've built is an interesting experiment, but not necessarily an improvement on the status quo, is commendable.

There is still lots to be learned from the work you did -- both the technical and the analytical. I think this is probably the most striking example I've seen recently of "negative results are results, too".

Thanks for the writeup.
