I have no idea, Sam. I suspect a "pounce concerning the evidence of Pitman. but I await your observation with baited breath. Meanwhile, Pitman also said that signals were not fired from Titanic while he was still on board her. This is crucial and of far more importance to this argument than when a particular life boat was ready to load and launch.That's what Lightoller said. So if they started to uncover at about 12, then by 12:20 the first one would be about ready for loading.
I think you know where I'm going with this.
And so, to "head you off at the pass" as it were; if you believe that QM Rowe had partly altered time then it is Game set and Match because if Pitman did not see any rockets fired before he left the ship in boat 5 and boat 7 left before boat 5, then it was boat 7 that was seen by Rowe at 12-25 am and signals had not been fired before that time.
It would not have taken Rowe more than 10 minutes to obey the order to bring the detonators so he must have arrived on the bridge no later than 12-35 am by his watch and the first signal was yet to be fired. That first signal could not have been fired any later than 12-40 am by Rowe's Watch which was partially set back.
