Hi Jeff,
I've been assigned to do an initial review of your "new correlation
metric" patch.
If I'm grokking the thread, it looks like Tom suggested a substantial
change in the approach (targetting per-index correlation rather than
per-column) [1], and although you agreed with the spirit of his
suggestion[2], there hasn't been a new version of the patch submitted
in response.
The result is, I'm not really sure how I should direct my effort here.Is it worth me reviewing the patch as it stands,
orshould I hold off
until a new version has been prepared, incorporating Tom's comments?
Cheers,
BJ
