Hookshot Tip Coordinates

At hookshot + 17C when the tip is in motion there are written 4 sets of coordinates, followed by their truncated averages.  This looks like
17C x1
180 y1
184 z1
188 x2
18C y2
190 z2
194 x3
198 y3
19C z3
1A0 x4
1A4 y4
1A8 z4
1AC trunc(avg(x3,x4))
1AE trunc(avg(y3,y4))
1B0 trunc(avg(z3,z4))
1B2 trunc(avg(x1,x2))
1B4 trunc(avg(y1,y2))
1B6 trunc(avg(z1,z2)) <-- The least significant byte of this determines get item value for pot chest
