Almost all the operators use the least EDTO that the sector requires. Most Transpacific flights can be flown at 180 minutes. There are some areas that 180 minutes doesn't fit so some will be 207 minutes (old approval but still valid) or 240 minutes.
The Atlantic would be 120 minutes minimum, but can change to 180 minutes if, for example BIKF weather is below minimums and another pairing is required.
The EDTO maximums are just that, most flights will have ETP's that are less than 180/240/330 etc
I recently had a flight where our EDTO was planned at 180 minutes but due to the times in the alternate forecasts the flight 1 hour behind is had to operate a 240 EDTO flight. So there is not much point in asking about a flights "EDTO minutes" because they change and then the only ones that will know are the pilots and the dispatcher.
