Can you contest an Army popup range qualification score?

My unit attended a rifle qualification range, and the popup targets weren't registering hits properly. I was not the only Soldier affected by it. I train a lot in my off-time, participate in shooting competitions, and train with others thousands of rounds on the AR platform every year. I would consider myself to be quite proficient at everything the M4/AR platform.

In my previous 5 years of the Army, I have never qualified with anything but a 39 or 40/40. This last time I went, I grouped and zeroed just fine, same as every other time. We went to do the qualification, which I shot 4 iterations of, never qualifying higher than a 27/40. One time I qualified 17/40!

My training room just updated my range score from a 39/40 to a 27/40.
I just dropped from 511 points to 421, basically blowing my chance of getting promoted to SGT out of the water in my particular MOS (25S, which is quite competitive).

So this stands to question, how do I go about contesting the range score? They can look at empirical data (my, and others previous range qualification cards) to see that we have never shot this poorly before, but what other way can I further enhance my argument?

I was told by one of the Sergeants in my unit that the range control told our acting 1SG that the range was messed up, but we shot and used the scores anyways. Not sure if that would help at all since I did not hear the conversation take place, but stands to reason it did if everyone shot so poorly.
