Isolation and single hex towns

[Blackcloud6]

I'm playing a PG: M game using the optional Unit Isolation rules from the AP website that Alan Sawyer wrote back in 2013. There is a rule about towns that states:

X.3 Isolation does not occur with units in towns or woods, unless friendly units have 50% control of the woods or town hexes. All other terrain has no effect on isolation, including units in entrenchments and dug in.

However, what about 1 hex towns and woods? I would think that a unit in a such a town that is surrounded would be isolated but a strict reading of the rule would be that the enemy does not have 50% of the town/woods. I recommend the rule be changed to read:

X.3 Isolation does not occur with units in towns or woods, unless friendly units have 50% control of the woods or town hexes. All other terrain has no effect on isolation, including units in entrenchments and dug in. This rule does not apply to lone, single hex towns or woods.

What do you think?
