Thank you @martins.vanags and apologies for the late reply. I have been busting my head over this trying to make this work, but I will need more assistance.
With the calculated measure you gave me, it shows me the number of days these tickets have been in their current status as you can clearly see here:

The number 30,85 reflects an average days in resolved state of tickets with the request type ‘blocked page’ that have been created in October. It does not show me how long these tickets were on ‘in progress’ or ‘new’, which is the information I need.
If I read your measure correctly, that seems to be the intent as you sum up the days in transition and the date it has been in this status so far.
The definition I now used:
