Blueprint graph execution order

In what order are all the events triggered in my blueprint? For this question we can assume that all the events are triggered simultaneously.

I have; Event Tick, Input Events (User defined action axis, action mapping, and ‘hardcoded’ key events) etc.

So how would I go about to figure out in what order my events are called (aside from debugging)? Are they always called according to hierarchy under the “Graphs” Group in the “My Blueprint” window?
