I have followed this distillation discussion here and elsewhere with great interest. So my 2cents (only worth 1 cent😛)
My conclusion is along the line of the post by @PEARL and quote by Rai (by the way very spritely for a 600 yo
).
There is just so much that influences the end result of distillation that the best method for deciding which oud is worthy is simply using your nose, feeling the oud and deciding if we will pay the asking price.
The history of the oud formation, the varieties, the locations, the difficulty in obtaining it, and technologies (some which are secret😉) and techniques around distillation make it most difficult to equate a value to the price of oud oil based on resination or the look of the wood and as such the oil is worth what people will pay for it. Use your nose
not your eyes
