Incognito,
In your Ops Manual FTL's does it state somewhere, to the effect, that an FDP commences upon report for duty and ends upon final on-blocks of that FDP/DP ..... and continues to state that there needs be a rest period appropriate to the previous DP before next reporting time?
If it does state this then the FDP start and finish times are clearly defined and if there is anything in the split duty definition that contradicts this then you may feel obliged to contact the regulating authority, the civil aviation authority, of the country concerned for clarification.
I can assure you that a 150% extension has never been intended.
