For what it's worth, I didn't get a chance to jump in right away when the testing thread opened up (lacking time and no spells) so I decided to test the system another way. Without casting any spells or using the parser, I'm looking at 4,4,1,6,1,14 in various skills as of today. I don't have any opinion on the matter, but compare this (with no casting XP) to what others are posting after a week or two of having extra casting XP.
1) Is there a noticeable difference?
2) If so, is the difference suitably large/small enough to serve our intention?
3) If not, what, if anything, should be done?
