I have a bit of an other opinion, but it will be a mess!
First spontanious elements will advance as either individual elements or as a column, the one in the front moves first. Let say they started all even. So you may choose which of the columns moves first.
I have started with I/J/K/L moving straight forward where it
must immediatly pivot around the point of contact to end parallel to the enemy it meets. (p. 30.) It then moves immediatly (not at the end of the movement phase) the extra 80p to line-up in close combat (p. 33). The column will follow like fig. 16 (p. 57)
I then moved E/F/G/H forward. But moving into the TZ of 5 this column had to conform to 5. I moved it the maximum distance of 200p. It didn't reach 5.
Moving A next, the column behind couldn't follow, so it moved separately.
Next, B could be moved in overlap, followed by C/D.
Ok? it is a mess, but it
is spontanious.
I hope I got it right somehow.
Of course by moving the columns in a different order it would be an other situation.
