The limits in ORO.FTL.205(d) are scheduled limitations.
You must be scheduled in compliance with all 5 sections.
The maximum extension is 1:00 above the limits in ORO.FTL.205(b) Tables 2,3 or 4; as appropriate; and may mot be applied more than 2 times in any 7 calendar day period, and may not be used in conjunction with Augmented Operations or Split-Duty Operations.
Further Guidance is provided in CS FTL.1.205(b).
With respect to your second question, I am unable to open the attachments; perhaps you can cut and paste what is confusing or contact me off line.
