I am not trying to GIVE the shooter a miss or a P, However OP states that
"With rifle, engage the 10 rifle knock-down targets".
"The first three rounds knock down the first three targets.
Shooter misses the fourth target with the fourth shot.
Shooter re-engages the fourth target, knocks it down!"
Meaning that Shooter did not engage all 10 rifle targets with the rifle as instructed shooter only engaged 9 of the rifle targets, #4 was engaged twice.
How could this not at least be a P for not engaging all rifle targets with the rifle. I shoot at several clubs and the unwritten rule for a target that falls or was not set before the stage is shot is that the shooter shoots where it would be. No misses. So u8nless the OP was posting the instructions different than written I stand by my call. And will gladly hand the spotting stick/timer to someone else if I am wrong!
