Configure campaing battle points

[a_ver_est]

I cannot fully understood the battle points option when creating a New long campaign, perhaps because my bad english. From manual:

"If you set Player 1's points to something other than XXX then Player 2's points will become a ratio of that number."

What means "a ratio"?, I have set player 1 (human) with 1250 points, If player 2 (AI) is set to XXX that means:

1.- AI will get less troops than player 1
2.- AI will get same troops than player 1
3.- AI will get more troops than player 1

TIA.
