I know that the Rest Period is the minimum period and that it starts when the last duty ends and must be completed before the next duty begins. All FDP calculators work on that basis: after input of block times it outputs the earliest time your can next be on duty. Therefore, what I have said above is correct. Except where your minimum rest has not yet been completed, a call before your next duty commences does not necessarily infringe the FTLs.
