Hi again,
I look at the graphs and see that on the 222/23rd a lot of data went one way then on the 27/28th a lot went the other way.
I do not know which color = in / out but this may help you find out if it is something one off or might happen every week.
One question is do you backup date Rayong -> Bangkok one day then Bangkok -> Rayong on different day.
I have asked Curt to see if this repeats often.
