The above is what HE claimed to find and ALL subsequent tests seem to corroborate his results.
That explains why people are 1: selling them and 2: buying them.
in short:
this is what billions of years of EVOLUTION claims to have found a good while before we even invented the wheel!
If there's one thing I hucking fate it's people who wipe their arses on other peoples posts/research as a matter of course, without doing any research on the subject of their own!
Go find some science that refutes this I dare ya!!

No where did I say anything about you.
My comments are specific to the CFD depicted.
I admit, I no longer know what 'aerodynamic engineer' means.
It seems like anyone with a 25-cent computer and thrift-store CFD can now qualify.
I submit that he's wrong.
His CFD is lacking.
Any conclusions based on the latter would suffer.
I know something about airfoils. I have the books written by the people who invented and tested them.
I've had the privilege to 'fly' some of them.
I know something about CFD.
People sell all kinds of useless ----.
People who buy useless ---- do not constitute scientific validation.
I've been wiping my ---- on this stuff since 1974.
It's the singular reason why I enrolled in a mechanical engineering program in 1976.
My senior project in 1980 involved aerodynamic streamlining specifically.
I've hung around the lowest drag cars on Earth since 1989.
I've hung around the fastest cars on Earth since 1989.
I've hung around the lowest drag human-powered vehicles on Earth since about the same.
I spent 4-years around military and research aircraft.
I've been a member of the Experimental Aircraft Association
International Human Powered Vehicle Association
Utah Salt Flats Racing Association
I've been in full-scale wind tunnels with my vehicles twice.
I built a Cd 0.12 car.
I have two Bonneville speed records and one proving ground speed record.
Tens of thousands of miles of road testing.
All my uncles were pilots.
My oldest brother's a pilot.
Neighbors and friends are AOA members and pilots.
I don't recognize any so-called science to refute, so it would be folly to pursue it.
We discussed whale tubercles here, probably a decade ago when it was fresh on the wires. I hoped it had died a natural death.
Like I said, you show me any FAA type-certificated aircraft on Earth using tubercles and I'll be all-eyes.
