I have noticed something while doing Battle Frontier. Say I have a couple of streaks in Battle Tower and then I do Battle Pyramid for a change when i get back to Battle Tower, the streak ig one and i have to start all over.
In order to get the symbols i have to start a facility and keep doing it over and over till i get it. If i leave and do something else, after some time, the streak resets.
