Just checking my math.

so I have RAF a--->b--->c---->d---->e
level 3 groups to 60
then level 2 groups on a b c and d to 15 and use the bonus levels to bump to 60
then level 2 groups on a b and c to 15 and use bonus levels to bump to 60
then level 2 groups on a and b to 15 and use bonus levels to bump to 60
and finally level 2 groups on a to 15 and bump to 60
just wanna make sure I am right
