I didn't know (using Blake Snyder's map) if the halfway point was going to be a high or a low (false victory, false defeat) but it turns out to be a high for my Protagonist.
He seems on top of his game, and the baddies seem overwhelmed for the moment.
All of which can only bode ill for him and his associates in the second part of Act Two.
Apparently the Bad Guys Close In, now, and we head to the All Is Lost point (around about page 70/75) which is the flipside of the HalfWay Point.
I don't know if I'll stick to his map, but it offers a loose structure to may shapeless thinking...
