One thing I've noticed that slightly irks me is that the Splatnet app shows
all of your Splatfest matches as being Flight vs Invisibility, even if they were mirror matches. I wanted to check and see how many of my matches were actually supporting my team and what my effective win rate was, but it's really hard to tell without remembering specific games.
At first I thought that the app just didn't show mirror matches at all, but that can't be the case. The app shows 33 Splatfest matches, and I know for a fact that I played 33 matches - I started the Splatfest with a fresh 1.5x EXP ticket active, used another one right when it ran out, and finished up with 7 matches left on it.
There's also this:
As you can see, the person called YAS QUEEN was on my side in one match, but against me in another. They were on my team several other times as well, as was NBroah. The Splatnet app even changed their titles to Team Flight titles. It does the same to the Team Power displayed under the results bar.
So basically, outside of remembering every single match, or taking notes, the only way to tell how many of your matches actually mattered is to compare the players on your team to players you also played against. For obvious reasons, that isn't going to work on every mirror match you have. I was only able to identify four mirror matches that way, and I know I definitely had more than that. This kind of annoys me, because I'd like to be able to see what portion of matches I played actually matters when it comes to the final results.
