If you've got the best lab in the world, you can use it one of two ways.
First, is to make the best oil that you possibly can, charge a bomb for it, and have 95% of the users throw it away 50-80% too early.
Second is to make an oil that jumps over every approval hurdle, reliably, every time it's tested...but only by a small margin.
Third is to pick a larger margin on second, and market it like the first, allowing plenty of room for profit, rebates,and knowing that most of your customers are never going to stretch your product to the margin.
They are in the third somewhere, along with all of the majors. Some even got caught on some sequence or another not quite being up to snuff.
