Ring and pinion set up question

Heel to toe is mostly affected by the cut of the gear and the alignment of the pinion bore machining to the carrier bearing bore. What you are looking for is the pattern to be centered between the root of the tooth and the edge of the tooth with a rounded edge on the pattern and not a pointed edge on the pattern.

The pattern does come to a point at the root side of the tooth. Not at all bullet shaped. I did increase the pinion shim to .022. It was .018, not .016. How do I get rid of the sharp point? Back lash is set at .008-.010. The ring gear is marked .008 from Motive.
