True as far as the turbulence's effect on pitch is concerned. But, when I play, there's an awful lot of air going somewhere - not a very small flow of air, and it seems to me it's going through the clarinet, at least as far as the first open tone hole or two. The pitch doesn't (or shouldn't) depend on the resistance to the air flow, but my comfort level almost certainly does in blowing against it, and reed response - the ease of starting the vibration - may be considerably affected by it. So, I don't disagree with you, but I think there may be more consequence of any cross-turbulence on other things than the pitch itself.
