I believe it will take the same amount of force to set the pins. What you're experiencing is a need for much more rotational force to overcome the locking mechanism's spring in order to pop the shackle (what you called an arc)
A good method I have used in this situation is rocking or wobbling my tension wrench from light to medium pressure as I pick the lock. You will notice as you pick that suddenly the plug will rotate just a few more degrees than normal, signaling that the cylinder is picked to shear line, then you can apply much more pressure in order to overcome the spring and turn the cylinder and pop open the shackle.
try this out and let us know how it works for you,

I tried again to open the lock with the key. If I start turning the key and I release it half way, the mechanism turns back and the lock is closed again.
The lock mechanism pull the plug back until it's closed. This is the reason why I need much more force to pick the lock with the shackle closed.
If I try the same thing with the shackle opened, the key stay in the position I
leave it.
Anyway, I tried to follow your suggestion about the wobbling tension. I don't know why but it works! I can pick this lock a lot quicker than with constant tension.
I tried a small diamond, a diamond, a small hook, a bogota and a ball. The best choice for this lock seems to be the ball pick. My bogota is too big to work within this keyhole.
I start with spp and wobbling tension, when I think the lock is picked but it's still closed, I give the pins a little brass and the plug moves a little, exactly as you said!
Thanks a lot Squelchtone
