It was specifically stated in the whole stark controversy that BY DESIGN, Stark is meant to create excellent cognition in diffused mode thinking.
The brain type and cognitive pattern you just described is typical of inventors, disruptors, innovators. They work on a lot of ideas simultaneously that even inspire each other… one idea can move all others forward, etc.
Innovation requires access to inspiration constantly, and a mind that bounces from idea to idea.
If you want laser-like focus, run a sub designed for that. If you want laser like focus on the ideas that stark generates, either run LE/BL alongside Stark, or use conscious guidance to turn that idea into motivation for your future and turn that into action
