monthlymax limit seems not fulfilled

[emvee]

Hi,

I am a new user and a new subscriber to the group. I have a toy project (just for understanding) with three tasks and three resources, say pa, sr and ds, with assignment pa -> task1, sr->task2 and ds->task3. The project lasts 36 months, from Sept 2019 to Aug 2022.

Now, task1 has  limits {monthlymax 10.42h}. However, in the resource allocation graph the effort of ap is 551h while it should not exceed 10.42h x 36= 375h (approx) according to my understanding. Further, I don't get why in Aug 2022 the scheduler provides a substantial boost while I expect that, without further constraints, the working hours should be evenly distributed across months (in my case since I set the limit).

Below you find my code. (For the other tasks similar things happen).

Am I missing something?

Thank you all.
