but now i made a new calendar with 10 hour workdays and still 5 days a week. but although the finish dates again got closer, the durations remained the same. this time wouldnt the durations change? because those durations were based on a 8 hour workday. but now i have 10 hourt workdays and the durations remained the same. how can this be? and if i need to correct something, what should i correct?
