Reasoning

Currently Sparkies on attack moves, and patrols, will chase after enemies that enter their GSR instead of reclaiming. Reducing the Sparkies GSR enables them to reclaim better in contested areas, using their gun to defend themselves while reclaiming.

Expected behavior

Sparkies should search for reclaim in a smaller area, and require enemies to be much closer for them to start pursuing.
In uncontested areas, they will require more precision to reclaim and may become idle sooner due to not going so far from the route to reclaim.
