The idea of using the pressure drop behind an obstruction, as opposed to the pressure increase in front of it, may have some merit though.
That is the whole point of the exercise. The dynamic pressure drop should equal the pressure increase on the pitot side. Will Bernoulli's equation cater for this? I suspect it will.

Just another "off-spin": Perhaps the inventor of this device misunderstood Bernouilli's equation?
Not quite an "under-arm bowl": He may well have done!
