Teamwork Feats in the Feat Description says
Benefit: What the feat enables the character (“you” in the feat description) to do. If a character has the same feat more than once, its benefits do not stack unless indicated otherwise in the description.
If my ally has the feat Coordinated Shot and I have the feat Enfilading Fire do the benefits stack for a +4 bonus on attack rolls if my ally is flanking?
If so and I'm within 30 feet, does the feat Point Blank Shot make the bonus on attack rolls +5?
