Yup. -.4 for .480
Crap.
I failed math.
Miserably.

Okie Dokie Smokies...!!! You both inspired me enough to go look up Stephen Holz's 2020 small block race.

My cam is bigger than 318 2bbl but not greater than .480 lift or 229 @ 050 so I deduct .4 (I had that correct)
I also have to deduct .4 for 060 overbore. (New deduction, I was unaware before)
I also have to deduct .4 for upgrading to SM heads
My NEW dial index is now 12.8, I still think I'm ok and once again proven the chart works :)

Now that we got that settled, I think the bigger story is the SM heads and results of the installation, wouldn't you agree ???
