app 5b

maybe some of you longer term BUY holders can answer this for me,as the company wont respond to my emails.
In last quarters activities,it claims $310.000 in revenue,but the accompanying 5B shows only $146,000 in revenue received.This appears to be the case in all quarters I have gone back through.I've been reading 5B'2 for years and have seen them vary with timing of receipt of cash v time produced,but this means some quarters would be up and some down in the 5B.BUY's are always only about half of revenue claimed.I considered they may be taking out expenses first before reporting revenue,but that is not how a 5B is meant to be arranged.Anyone know where the rest of the money goes?anyone know if the claimed $600k a quarter soon to be coming from kiliwani will also only show up as half that amount in the 5B's?.for the record,I have held but not for a while,considering this may be the time to re enter,given potential production.
