# Definitive answer on how PR Weight works.. (almost) (in General)

## AdminNightStrikeAugust 26 2007 3:48 AM EDT

So here it is:

PR Added = MPR(PR Weight / 100 * Enchantment * XP on minion + total XP) - Current MPR

Where MPR() is the function for converting from XP to MPR already in the wiki.

Now, this will be off by about 100. There's probably something else I'm missing.

lol is it +100?

Yeah, my estimate on the test case was 4165, and the actual was 4055.

This may be correct for calculating PR added if that is the only item used. However the more nw added PR already on the team the less PR further NW adds.

That's probably because NS left out a sigma symbol in the formula. I bet what he meant is:
PR Added = MPR (sum(PR Weight/100 * Enchantment * XP on minion) + total XP) - Current MPR.
In other words, you calculate the "XP" each armor item adds to your team, add all those "XP"'s to the actual XP the team has, and then calculate the PR, using the MPR formula.
