> After hating how each company runs on an internal quarterly cycle

In 25 years of working professionally I've never felt this or heard this even once.

> execs every 13 weeks, maybe they can focus better.

I don't care about the struggles of executives. I'm entirely unconvinced that an additional two weeks a year will afford them enough "focus" to make any appreciable difference.

> that takes 3–6 weeks after quarter end to churn out reports.

We run a sales heavy organization. No one "churns" out reports and hasn't for decades. The biggest struggle is getting engineering to finalize their existing capital project reports. Everything else is automated to such an extent that I can't even fathom this scenario still existing.
