Yes, it all depends on how many races you have to go and how big your pack is. We have 6 races for the den, 6 for the semi finals and six for the finals. We also ended up racing three more times in an overtime heat. My daughters car had the 4th fastest average overall in the den races, but had the fastest car the rest of the way. By the overtime, other cars slowed a bit, we were just as fast as we had been. And of course we had bad luck in the end! But that’s a whole other story, lol.
I think there's a good chance this was related to the graphite, but a confounding factor in Scout races is that your scouts' cars might have been better in traffic than other cars and it wasn't noticeable in the first six races, because your scouts cars took an immediate lead. I don't feel like you really know how fast the car is until it races against other fast cars.
