Your absolutely right. I have often heard windshear reports of "plus or minus 10 knots" That is of course turbulence.
Windshear however does not have to have a certain magnitude threshhold to be windshear. A loss of ten knots low down could ruin that greaser. It does not have to happen faster than the aircraft can accelerate. just faster than we poor buggers can react to it.
Off to the pub now chaps it's POETS day
