You are by no means the only team to experience this.
As other mentors and team leads have said before, the whole of the match would need to have been seen by all to make assessment. That being said, your overall performance would reflect your abilities. When we "Active"ly scout teams, not just in the pits, we see for ourselves how each team performs from the stands and log it into a program that we write. All teams, us included, can tell all other teams in the pits that we can do everything. All I will say is “the proof is in the pudding!” even though your robot may have the capability programming could work against you, you could have a mechanical failure or even a human malfunction.
All of these things work themselves out as far as “Robot Performance”. Now sometimes the algorithm works in your favor during match play and sometimes not. BUT remember what I said about “ACTIVE” scouting, it does reflect the true data of team and robot performance. Don’t waste your energies on a single team that is full of themselves. If you show grace to them, then that displays your gracious professionalism!
