This effect caused a very low and nervous first flight for a friend in his
new Mark III. He had mounted a commercial combined static/pitot probe on
the front of his nose cone. It was about 6 " long which is more than
enough for a wing mounting but in front of the much larger radius nose
cone put it in stagnant air. The resulting low pitot pressure had him
thinking he was on the verge of stall all the way around the pattern when
it turns out he was doing over 80 mph.

Tom it was good to read your comments.
I did about the same thing when I first flew my mklll. As I remember the
pitot worked ok but the static pressure was high... by disconnecting the
static tube and letting it vent inside the nosecone things were much closer
to normal.. I then moved the pitot static tubes to under the nose cone
to correct the problem..
