You would still have to find out which pin stack contains the torpedo-pin. The torpedo-pin is not necessarily the last pin giving marks; as you can see in my animation, pin 4 (torpedo pin) gives its last mark at frame 19, while pin 2 and 5 (regular pins) give their last marks at frame 20.
Your comment does lead to an interesting thought; is it possible to distinguish which pin is the torpedo-pin during impressioning, just by its behaviour? I think it might be possible, but I'd have to investigate on a few locks with different combinations of pins. My guess:
When the lock goes into a "false-set" state during impressioning (say 5-10 degrees of rotation on the core), in the following steps, mostly the torpedo-pin will be binding and making marks. Only just before you hit the "catching" action of the torpedo-pin, it might allow a few other pins to mark, those are not torpedo-pins.
For example (see animation):
Step 1-12: normal impressioning, alternating marks on all pins..
Step 13: lock core goes into a "false-set"
Step 14: mark on 4
Step 15: mark on 4
Step 16: marks on 3 and 4
Step 17: mark on 4
Step 18: mark on 4
Step 19: marks on 2 and 4
Step 20: marks on 2 and 5
Step 21: no more marks
In steps 14-20 (after the "false-set") the majority of marks are from pin 4, so that would be the torpedo-pin.
Time for experimentation, we're getting somewhere!
