It might be more constructive if you based your insinuations on fact instead of pure speculation. Do a little research first if you're going to make spurious remarks.

That's my exact point. What are the facts? Lets see a tunnel commissioning report, lets see the data reduction methods. Q control etc.
I have done 10 years of aerodynamic research in many different tunnels, scale and full size, rolling road and static ground. That's why I am concerned.
It could be I have no reason to be concerned, it could be that full disclosure of the testing limitations is fully explained to all customers. But I all I see is pictures of 2 and 300 mph (and some 400 mph) cars in a tunnel only capable of running 130mph with a blockage ratio of over 20% and the tail section of the car way into the collector of the tunnel in some cases, with what looks like a distributed suction system in the floor on a static ground. With comments like "some good downforce gains found".
Perhaps it's not me who should be doing a little more research.....
