Yes, this seems like a major flaw with the grant proposal data discussed. Young professors and grad students are often really busy during work hours, and don't necessarily know all their deadlines well in advance. If you give them a six-month window to write a proposal, they'll probably work on it incrementally while fitting in as many other deadlines as they can. Obviously procrastination happens, but it's also possible to get last-minute submissions from good time management; people use the full time available to create more space to get other work done.
