Do those formula take into account meplat or only total diameter?

I know Elmer Keith was not a scientist by today's standards, he did however understand that the meplat on a bullet was one of the most important attributes to its penetration. Keith liked the meplat at 70% of the bullet diameter as any wider and it would hinder penetration at the velocities he used.

One of the bullets I want to try is the 300 grn WFNGC from beartooth. A hard cast 240 LSWC at 1400-1500 FPS will penetrate any North American game animal, provided the cast is not too hard and brittle.
