It depends. If the two of you are far away from one another, then each of you are affected only by your own game stage. You will get zombies staged to you, they will get zombies staged to them.
If the two of you are together in a party in a small area, then the game will list your gamestages from highest to lowest then multiply down the line by a diminishing value, then add the multiplied values together.
So, you have 532, your friend has 250..
532 x 1.7 = 904.4
250 x 0.85 = 212.5
Then we add together,
904.4+212.5 = 1116.9, rounded to 1117.
So if the two of you are partied and together, you'll get zombies staged for 1117 gamestage- This might seem unfair, but, honestly, two players working together against zombies is a HUGE benefit that this gamestage multiplication doesn't fully account for.
Anyway, Here is the excerpt explaining it from the gamestage.xml
