If we present this professional linesperson as an example of model behavior, then we might as well follow her lead and loudly and clearly
announce "out" when the ball hits the back fence. That way our opponent and any spectator will clearly know the outcome of the point. Why sneak in a quick flash of the index finger?
Alternatively, I have found found it helpful to place those huge foam fingers
near the back fence during my matches. I use it to signal out using that whenever my opponent's balls hits the back fence. I wouldn't want an argument to ensue because it wasn't clear to my opponent that his ball was out.
