I don't really understand the small number of votes. A number of people (like yourself) have written fairly clear assertions in this discussion, but seem to have been for some reason 'frightened' to vote (or 'frightened' for their vote to be seen?) - even though there were "don't know" and "it depends" responses available.
John - if you really want to know for certain, then set up the simple experiment I described. There is a perfectly valid reason why the Willis is designed the way it is, to act as a sort of pump.
I've been very busy recently, and that's likely to persist for a while, but as soon as I have got a bit of time I do intend to conduct some experiments, but somewhat more complex than you suggested - so 'watch this space' (but be prepared to be a little patient!)
Good, it would be nice toget to the bottom of it. or should I say, become more informed, all of us.
I am surprised that many people expressed opinions but yet did not vote (unless like me made a mistake) , those ascertains 9whether I agree with them or not) should be there in the vote ideally so we can judge an outcome.
Personally I have no objection to my vote being seen even if I turn out to be totally wrong.
Every opinion counts it really does, whichever flavour, it is important.
I would rather I be proved wrong than nothing proved at all.
