Are the STR Pundits Correct? How many hours per STR of work you put in?

[Pretty Khare]

I have been researching how feasible is self-managing a STR with a demanding fulltime w2 job (50 hours/week). STR pundits such as Robuilt and Short Term Shop tout that once you have your processes and core team setup, you can automate most of the work with Technology.

Those who self-manage, can you please mention your average hours worked per STR after it has been closed and stabilized (after furnishing and listing etc.)? Thanks
