7-23 Power Package Delivery Path

[sustainthelag]

1. 7-23 in TGM says "The three possible paths of the Hands down the Inclined Plane (10-23) are the Basic Delivery Procedures...". I assume two of them are LINE Delivery Paths and CIRCLE Delivery Paths. What is the third?

2. Second paragraph says "Normally, Delivery THRUST is Cross-Line--Delivery MOTION is On Line." I'm a swinger, so my question is from that point of view. Can a swinger use a LINE Delivery Path? Assuming no #1 accumulator, why is the THRUST considered "Cross-Line"? Since my aiming point is on the plane line, wouldn't my thrust be on plane? I'm just not understanding LINE Delivery paths with the swinging procedure.
