Prestiging - multiple attackers

It is calculated on the CP of your highest CP mon of your entire team, in comparison to any mons you attack.

You get max (1000) for keeping at or below 50% CP of the mons you attack...and decreases the higher the CP of your toughest mon is compared to the defenders.

Let's say, I beat a 2200CP Blissey with two 1700CP attacker. How much prestige points does it give?

--> Assuming the 2200 CP Blissey is the ONLY mon in the gym and there are no mons exceeding 1700 CP in your 6-man lineup, you will get 647 prestige points.

Then I weaken the same Blissey with a 3000CP attacker, then switch to a 1000CP one and finish Blissey with that one.

--> Switching doesn't matter. In this scenario assuming that your highest CP mon in your 6 man lineup is 3000 CP your prestige gain is 367 points.

What if I weaken the Blissey with the 1000CP attacker then finish her off with a 2200CP attacker?

--> 500 points, assuming your 2200 CP is your highest CP mon in your lineup.

How much points do I get if I beat the 2200CP Blissey with 3 1100CP attackers?

1000 points, assuming no other attackers exceed 1100CP.

GamePress doesn't seem to detail these real-life scenarios.

--> Yes ok but you can work it out right?

Just to beat a dead horse: the highest CP Mon in your team is the only one that figures, even if he doesn't throw a single quick attack.
