Yes, the "premium" adjective was describing the dimension, rather than the furniture, as I now understand it.
I was going to post earlier, but didn't, that a 3-4" thick table is somewhat an irresponsible gluttonous use of timber, IMO. I'm even considering taking my premium figured Blackbutt boards down from 44mm (dressed) to 18-20mm by resawing. Just for a start, it will be too bloody heavy even at 44mm!
