Optimizing Focus and Collaboration Time of IC to 92% in Software – Feasible?

I recently wrote an article outlining an approach to achieving a 92% focus & productive collaboration time in software engineering. It's a strategy involving cutting meetings, aligning schedules, and more. I'd genuinely like to know what fellow engineers and managers think about these ideas. Have any of you tried similar tactics? What were the outcomes?
