without having to do a lot of math(well more than adding and subtracting)when you are in a group the lowest person to know if they can get exp is take their lvl, cut it in half, and add that to their current lvl #. so say if you were a lvl 20, you would +10 to that so that your highest lvl in your group to possibly get exp would have to be lvl 30. and if you were lvl 30 youd +15 to your lvl # and come up with that you could only group with lvl 45 and under.
for those who prefer math....
(lvl)/2=A
A+(lvl)=Maximum lvl
----------------------
ex1.(20)/2=10
10+20=30
----------------------
ex2.(30)/2=15
15+30=45
hopefully that helps
