I've been doing some analysis with my ND and there si a point I can't understand. I work with a field cost drive_time, where it stores the time spent to cross a segment. The first analysis was made only through this field and the results where OK.
The second analysis was made through the same field but stablishing Start time and Finish time (windows time activated), so I would like to know how many stops are before the finish time.
The results are different from the first analysis. It takes a different route in both cases and I don't understand why.
Thanks for any help.
