what percentage does tim on trees, page-8

thx for your thoughts....but does anyone know what percent of eaqch dollar raised for Forestry actually goes towards the trees themselves?
Whilst it is highly relevant what %age of TIM's MIS's are trees...I think another key (but kinda missed by most people) point is whether or not they spend 70% on the trees?
If it's more...fine.
If it's less....
1. well you're either going to see a big hit to the bottom line as TIM will have to spend more on trees and less to the GP, OUCH
or
2. the ATO are going to disallow that particular MIS. OUCH OUCH

any thoughts?
