It seems like a decent guide, though like others mentioned, you should download and run the code most of the time, except for trivial changes.
Also, I'd like to push back on this:
> Most developers have a lot of features to add and bugs to write, time spent reviewing other people’s work does not add a lot to your bottom line.
I disagree; it adds a lot to your bottom line. In fact, reading and reviewing code is one of the main tasks of a developer, perhaps more important than writing code.
Reviewing code gives you an opportunity to get familiar with other parts of the code base, understand why a change or fix is done, and collaborate with others to make an overall better improvement to the product.
It gets frustrating when egos get involved, and people take criticism too personally, or point out improvements for the sake of demonstrating their knowledge. In best working environments, code is judged without a bias or relation to who produced it, but as an inert output of the collective team. I would actually like to see a feature in code review tools to submit merge requests anonymously, just so that the author isn't a prevalent factor while reviewing. :)
I usually dedicate a few hours, maybe even half a day, to reviews. Definitely don't look at it as a chore to put off, but as a crucial part of your responsibilities as a developer.
