Hi, @lpb
About durations in Gantt view
Set dependencies and entered durations.
After that,
First, move the predecessor task backwards.
Then, move the successor task forward.
As a result, durations for the predecessor task was reduced.
I wonder how this calculation works.
I think it’s a combination of avoiding holidays and automatic scheduling.
Attached is a diagram of how it works.
When I reproduced the above behavior using PMtool, which is different from Asana, the result was as shown in the following figure. This is the state I want to be in.
