Just had a few spare minutes to take a look at having different delays between transitions.

The code has been modified in the FSM node so it outputs msg.delay which is used to set the variable delay in the delay node. You need to change the option in the Delay node to... "Override delay with msg.delay"
Please note:
The delay values in the FSM are in milliseconds.
If I had more spare time I would introduce a variable called 'defaultDelay' so you could use that in the paths of the FSM where you didn't need a different delay. Hope that makes sense.
Well that was easier than I thought, so here's a flow with a 'defaultDelay' of 1 second.
