It was recently discovered that Scott can give a maximum of 4 points at the Battle Frontier (previously thought to be 3) depending on how many times you encounter him throughout the game. There are a total of 13 encounters with 5 of them being mandatory. Someone updated his page on Bulbapedia with the encounter list and how many points he gives out: https://bulbapedia.bulbagarden.net/wiki/Scott#In_the_games
If you can find a way to track this, that would be great!
