That's exactly what I've been trying to figure out... how much a boost in stat score will raise DPS -- then you have a metric for how worthwhile an upgrade would be versus the time or gil required to get it. I’m not talking about BiS gear, but for the incremental stuff, it’d be nice to have a sense if spending X gil or X tomes will have an effective difference before making the investment.

Obviously more is always better, but when cost is a factor you’d want to make smart decisions, too. So does anyone have a guess on the significance of 2 weighted stat points? 5? 10? Normally 3-5% is considered statistically significant, but I don’t know if that’s a concept that holds up in game.
