Hello Youngster, glad to see you are still at it regardless of the great assistance and positive feedback of too many (misguided) Veterans of this forum. How can you not succeed with such youthful commentary coming from adult (aged) mouths?
Signal your finger (count) when you have the attention of F1, with palms facing in. This will show only your count fingers (try it for yourself), easier to see especially at a distance.
Watch out for the “Strike” hand over the head of F2; he may popup on you with a throwing arm or his head.
No need to look at your counter; takes eyes off the field. Cut into the wheels notches for the zeros so that you know when you are reset there by feel. If you need to look at your counter, pull your hand up to your mask, counter facing in, and peek as you adjust your mask
Get an F2 that can catch; those wiffle balls can put a sting on you and Mom’s furniture.
