You need to feel and understand what is happening.

Machines, well until you you can see where the high ground is you are apt to drive them directly into the bog (but you will have succeeded in getting there fast)

These guys, the stump and the puck are great for shrinking shallow curves, working from the inside of the panel.

When you get to a high crown area the edges of the panel start getting in the way.
You can shrink by putting the hammer inside and hitting it with the puck.

I mean use a post dolly of appropriate size like the one below and hit the work just off the point of contact with a wedge shaped soft hammer (wood or plastic) the plastic hammer in the pic has one wedge shaped end.
