If those odds are correct ... and that's a big if ... not only does it mean bad things for the base / but the base auto print run is simply ENORMOUS.
Purple autos are only available in Jumbo cases ... so we can take the odds 1:1080 jumbo packs and figure out just how many Jumbo cases.
42 prospects * 10 Purple autos per prospect is 420 Purple Autos.
Odds of a Purple auto are 1:1080 packs (or one every 11.25 cases). 11.25 cases * 420 autos and you get 4,725 Jumbo Cases.
Bowman would have printed at least that many hobby ... likely more. You're looking at roughly 10,000 + total cases. Absolute madness.
