I came up with a solution that creates 2 loops,one stamps following mouse point and the other does the same but set X to (Mouse X + 100),and they do the work at the same time.

it kinda works,but it's not as smooth and fast as I thought.

Does anyone can come up a better solution??

actually my question is not clear

it's more like stamp twice every 10 steps following mouse point,not just stamp 2 times…
