Sorry for the double post, but I thought you might be interested to see this.
MaRo has posted the odds. So looks like 8.88 packs per draft will have 2 rares, 0.96 packs per draft will have 3 rares, and <0.24 packs per draft will have 4 rares, for resulting in roughly (8.88 + 0.96*2 + 0.24*3 =) 11.52 extra rares per draft.

All good! Thanks for sharing. Ultimately still too much variation, imo.
