Default not stretching when planishing

Hi Chris,
Stretching seems to happen along with planishing.
I've seen the stretched panels from some "top shops" out there.
The wheeling machine does stretch when planishing, and I have seen that from some top shops, too.
The pneumatic planisher hammers also stretch while planishing, although with some knack there can also be some shrinking.
The pneumatic hammer I use is fine for planishing without any stretching, and is also fine for shrinking while planishing.
Lots of ways to skin that old cat fish.
