No joy, unfortunately. In thinking about this a little harder, I have realised that no-one is going to sit down in a micro-second, so perhaps it would be a little better if the reading were only taken every, say quarter of a second, that way the people also have time to sit down, as in the current model if they sit down gradually, the counter won't count them. Is it possible to do this, preferably without delay, since that will cease the whole program, instead?
