I've looked trough some of the ores that are listed and found some things that doesn't look right. I've heard that you did the weights using actual in-world generation values, so that's fine, but the ore types seem to lack some things including:

-harvestcraft salt
-Project-Red peridot (I wouldn't care, but all the other gems are listed. Also, the comment on the list says there's such thing as project-red olivine, which I've never heard of.)
-Railcraft saltpeter (Entirely different function from salt, but only generates in deserts. Listed since there are also emeralds, which are supposed to only generate in Extreme hills)
-A bunch of things from Nether Ores are missing, such as nether emerald, uranium, ruby (And a lot of other gems), amber and sulfur. You also registered malachite to the nether ores, which is probably the cause of #1108
-Nothing from bluepower is listed (Unfamiliar with the mod, but I know it adds bluestone, so there might be other ores that are unlisted)
-BoP ores. Most of them are useless, but some of them are already generating because of the similarities with Project-red ores, so it would be nice to do the rest just for consistency.
-Charged certus from AE2

These are from the more popular mods out there, but there are also things like:
(Note: This part is more of a suggestion. If you don't want to do any of these, that's perfectly fine.)

-metallurgy (Ugh.)
-Mimicry
-gems+ (Not as popular as the others, not even sure if it uses oredict, but registering all of the gems would probably cover a bunch of other mods.)
-possibly poor/dense ore support
