D&D 5E sharpshooter math meaning

I missed it: what's the narrative that repeatedly works for Sharpshooter's -5/+10?

There are several outlined in this thread, and I'm sure you're able to think up others. Pick the concept that you like the best, or ask the player using it how they see their character doing so.

Again, I missed it: which ones made narrative sense in the general case?
