If your schedule is busy enough, you may literally not have half an hour free between now and the half hour being booked. Calendar UIs are pretty good at making it clear whether you're finding an open one-hour slot and less good at making it clear whether you're finding an open half-hour slot where there's a free half hour at some prior time. And they also won't put a hold on that half hour, so multiple people might send meeting requests that implicitly expecting the same prep window. You can potentially build a culture where it's normal for the recipient to decline invitations if they can't find a prep time, but it's much more coordination overhead. Also, there's an advantage in having the document fresh in your mind, instead of shuffling into a meeting with people grabbing sodas etc. and immediately hearing "So, any comments on section 1." (The article mentions this: "Some people read the document but forgot what it said because they read it days or hours before") Maybe another way to put this: "respectful of time" does not mean allowing the recipient to cram as many things as possible into their working day; it means allowing the recipient to decide how many things they can pay full attention to. If they don't have a full hour to dedicate, the better answer might be "Let me find you someone else who can provide you feedback" (or declining some other commitment in order to prioritize your document) instead of showing up for half an hour.
