Scenario: 4 day RES block, 1 X-day, 4 day RES block.
If I am not contacted (human) of a prospective 30-hr rest period, what is the formula to calculate legality?

I started LC at midnight day-1, so it should be simple. Making sure that I'm not legal at 00:01 on the third day of the second block. (day 8)(correct?)
I was used for a 3-day in my first block w/o a 30 layover; nothing on my calendar except LC at my 30-min post-flight schedule check.

I haven't acknowledged the CNO voicemail they left me, (didn't read or acknowledged the CNO text in MiCrew) and haven't logged into iCrew since my trip, so per MEC Alert 25-01 (most recent document), I haven't been notified of the 30-hour rest that is sitting in MiCrew.

BTW, thank you for the 'Required call' -v- CNO discussion. tennisguru: your post #2844 is an awesome, simple outline to follow!
