Bonus points.

I won a game with 4 tries and opponent had 2 tries. I have only 4 points for this win. is it ok?
I know that I must have 3 tries more than opponent but thought that 4 tries anyway guarantee 5 points
To get the try bonus point it does not matter how many tries you score, you only get it if you score 3 tries more than your opponent.
Thanks
