The 160p is because this is two chariot or Elephant base-depths. 
I'm measuring from the front corners, because that's where the hypothetical overlapping enemy Elephant/chariot's front corner would be. You then measure the hypothetical chariot's base depth (80p) and recoil (80p) from that point.

Ok. I see. Yes, I agree. I think this shlould be the way to decide when you are or you are not overlapped by a ghost
. Could someone check this is what Phil was thinking about when writing it?
Thank you.
