None of those results suggested better 'move ordering' (FH%) with worse move ordering. >The hash move is often _not_ a capture.

The reply to the noncapture will be an instant cutoff as well in most cases, since you have a hash move in that case. If it's a capture, and the correct reply is a noncapture, you're screwed without hash. -- GCP
