what the heck is a grinding calculator?

i found this digging through the wiki...

http://wiki.guildwars.com/wiki/Talk:...ing_Calculator

so i downloaded and scanned it seems to be clean. but no instructions?

any ideas?

well im gonna go out on a limb and say all you have to do is plug in the info hit calculate and there you go...

I don't mean to sound rude or anything here, but what instructions do you need? You put in your characters current level in the top box. Then you put the level you want your character to be in the second box and click the button. It then tells you how much XP you need and how many foes of a certain level it would take to obtain that level. It's pretty much useless as far as I can tell, and to fully serve it's purpose it should have another box for number of party members.

PS: You do realise you need to unzip it first, right?
