Why the visit count matters more than the percentage
A share of the session says how much time a reading spent in a band. It does not say whether that time came as one sustained stretch or as repeated brief excursions. Here the reading entered the zone above 70 21 times and left it 21 times, with a median stay of 2 minutes and a longest stay of 25 minutes beginning at 09:31 ET. Below 30 there were 9 visits, a median of 2 minutes and a longest of 6 minutes.

What this is and is not
This is a record of where one indicator sat during one completed session. It is not a forecast, and it makes no claim that any reading preceded a move. Whether crossing 70 tends to be followed by a larger move is a separate question, measured separately.
