 Min level = Look up the level you'd be if you were fighter2 (and no add-ons like double XP), then subtract 2.  e.g. Min level for 8 KXP is 4-2 = 2. Min level X means you can be level X in one class, or X-1 in up to four classes.  e.g. if min level is 10, you can be level 10, or 9/9/9/9. 

Max level X means you can be maximum of level X in one class, or X-1 in up to four classes. e.g. if max level is 10, you can be level 10, or 9/9/9/9.
