Thanks Dude, but I wasn't referring only to you. I also like to put a bit of caution to my estimates but most of the math I see points north of twenty. I guess it doesn't roll off the tongue as nice as zen to ten though.

On another note, I wonder whether the 30% may be more based on available flake size which meets those specs without too much milling or being smaller. The other flake sizes could be better suited for other applications? Would appreciate feedback on this question please.

Thanks,

Ed
