Is this extra movement part of your move, or is it an additional, separate move?
Example 1.
An enemy element is just outside difficult going. To contact it lined up I must enter the difficult.
I am cavalry in good going, moving 240 in good, 80 if reaching difficult.
The distance to a lined up contact is 200 paces.
The distance to partial contact without entering the difficult is 180 paces.
Can I move 180 in good going to partial contact, then use the 80 p extra to line up?
Or does the fact that the extra 80 p ends in difficult mean that I can only use 80p of normal tactical movement in the first place?
Example 2.
I move through a 1 element wide gap between two enemy side edges.
I partially contact an enemy element with my front.
Can I use the extra 80p to move sideways and line up?
