This has not been my experience, not at least in research or IT/research sector. More hours do not translate in more results _or_ more focus.

I've seen also an inverse relationship in quality of work and work streaks also in other fields, for example a direct experience for me was automated textile production. More hours in this case has a direct relationship with more product, but results in more stupid mistakes and more importantly I've seen less overall feedback from the production line, where employee are just more eager to say "fuck it" and simply do the work as opposed to try to help in improving the production process. There is a fine line between using your employees as a resource or a brutal work-force.

This was an eye opener for me. There is definitely a balance in every part of the production line, and less work is generally good for everyone.
