USA-pocalypse radiation effects?

[curtis006]

How exactly do the radiation effects in the USA-pocalypse map work? I saw someone get a -2 and a +1 on their very first turn, yet nothing on the key for the radiation effects shows this as possible.

thanks

If you own one or two radiation territories you get minus one on your drop. When you own three then there is nothing subtracted. Once you own four you receive a bonus of 2 additional armies. Own five and receive 5 additional armies. Own all of them and receive 9 additional armies at the beginning of your turn.

If you look to the lower left of the map there is a triangle sign that shows this.

The radiation effects build on one another. For each single irradiated territory held you lose 1 army. For each pair of irradiated territories held, you gain 1 army.
If you hold 1 irradiated territory: -1
If you hold 2 irradiated territories: -1 for each single territory, and +1 for the pair (-1+-1+1=-1)
If you hold 3 irradiated territories: -1 for each single territory, and +1 for each pair (AB, AC, BC) (-1+-1+-1+1+1+1=0)
If you hold 4 irradiated territories: -1 for each single territory, and +1 for each pair (AB, AC, AD, BC, BD, CD) (4*(-1)+6*1=2)
If you hold 5 irradiated territories: -1 for each single territory, and +1 for each pair (AB, AC, AD, AE, BC, BD, BE, CD, CE, DE) (5*(-1)+10*1=5)
If you hold all 6 irradiated territories: -1 for each single territory, and +1 for each pair (AB, AC, AD, AE, AF, BC, BD, BE, BF, CD, CE, CF, DE, DF, EF) (6*(-1)+15*1=9)

This should be posted in the map thread, but I was unable to find the thread. Basically what is happening, when the map was made, people did not know how to code the complex XML needed for this, so they just counted each bonus sequentially.

Ah, I see now. Thanks for explaining that.
