You can try the below measure

Avg num PRs =
AVERAGEX (
    VALUES ( 'Stories'[Story ID] ),
    COUNTROWS ( RELATEDTABLE ( 'PRs Stories' ) )
)

This assumes that a PR can occur in multiple stories but can only appear once per story.

Put this in a visual with the story points column and I think it should work.
