Thanks for another way of putting it Ualaa, i have read some of the other posts that have been posted and seen MiRai video of it on youtube also. Also Ualaa i noticed on my lavishsoft subscription history in 2010 that i had your name as Referral
One set of boosting grant levels equals in levels:

A 75 < B 70 < C 60 < D 40 < E

Or

A 60 < B 40 < C
A 60 < D 40 < E
so total 120 levels from one boosting session. I know you cant give levels higher than your own level so 2 boosts (minimum) would be required to get full benefits.
