I’ll chime in.
Account 1:
WSB is clear. Have to shoot first string Strong Hand after reload. There is no “OR” stated for which hand to transition to. It says “Strong Hand”. Shooter transitioned to WH. 6 procedurals.
Account 2:
Shooter believes RO was coaching when RO stated (Paraphrasing) “Be mindful of what you do for string 2, you just got 6 procedurals.” Shooter Arbed rule 8.6.1 Coaching. There are no grounds for a reshoot under coaching. In fact you as the shooter can get a procedural and or the “coacher”. I’m sure the Shooter/arbitrator wasn’t trying to accumulate a 7th procedural as he took the ROs advice on how to shoot string 2.
Arbing for RO interference (a different rule) would have been a better platform.
