believe the 3rd is the average value in the time covered by the graph (35 minutes here), and the 4th is the width of the graph in minutes, how much time is displayed (35 minutes)
Yes~ Originally I thought it was the average of the first and second data on the left
But it seems not.
According to the precise calculation of designing the AQS program, there should be no error at all.
I upload another picture below~
(46.78+44.09)÷2=45.435
The display is 44.69,
I don't quite understand what this number means.
ΔT generally represents the difference between two time endpoints,
not used to express a certain period of time,
Then △ this symbol will become meaningless~!
My point of view.
