Nice work so far! It's neat that you've already been able to spot changes. A couple suggestions for the graphs. It would be nice if the graphs had an arrow indicating the "good" direction (i.e. which direction of movement is = an improvement). Also, a graph of the derivative of the curve might be interesting for at a glance trending. -- Brooks --EuxKj2iCbKjpUGkD Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQFHl50AXY6L6fI4GtQRAktvAKCDpZyshqkBGYG6Bz5jRKPyIhVl1ACeJPbn rcsV0rgZMPQhmLxNLl34FIc= =iGt2 -----END PGP SIGNATURE----- --EuxKj2iCbKjpUGkD--
