In the shotgun sports - skeet, trap, 5-stand, and SCs, where there are many birds thrown on different angles that need different leads, they are called crossers, not deflection shots. I have never seen that term used in 50 years of shooting the shotgun sports. Wikipedia has it a bit wrong using that term. Deflection is something being deflected from it's original course. Leading a target is just that, and there are many different ways to do it. A couple are swing through, maintain lead, pull away, intercept, reverse lead - you get the idea. Wikipedia isn't always right.
In the future you may want to pick a different term.
