Time+Distance screens close to the ball carrier

[JugglingReferee]

You're the Lead, ball is up top. Some screens in the Trail's area too, with good ball movement

In your PCA, there is some action too. Screens from the low post to the high post, vice versa, and some across the key as well.

Your experience tells you that an entry pass isn't coming, but rather a pick and roll up top. Sure enough, it comes, and a screen is near the ball carrier. You believe t+d wasn't given, but the screen is pretty close to the ball carrier.

How far away does this screen have to be before you'll call it from the Lead? (And fwiw, you think your P has already missed 2 of them this half.)
