Good question. Homer explicity says to zero out accumulator #3. So the answer is less than 4!
If I think about it, there is no wrist cock either, so that eliminates #2.
I think the answer is 2. You should use accumulator #1 and #4 while executing 12-5-1.
Trig,
I was trying to figure out how Acc. #4 was involved in a stage one stroke. Then I referred to 6-B-4-0 and read this; "Left Arm Power in any form or amount can still be considered #4 Accumulator Action."
So, yes Accumulator #4 is involved in the two barrel stage 1 motion.
I learned something today, now back to answering the pro shop phone.
