That's correct but that criteria only applies to the standalone pathologies. By that I mean, an unsub who doesn't drift from one to the other. Yes a two day cooling off period is a very short one but it's still a cooling off period. When Bulford started attacking victims one per day that's when he turned spree killer. He had reached the three victim body count, so he was a serial killer and it was the rapid succession of his later attacks that determined his status as a spree killer. When it comes to serial-turned-spree killers, however, I don't think purely body counts are what define the unsubs or that to be one, an unsub must reach a certain body count. If you look at Megan's victims, (now I'm not really familiar with her so I'm just going with the page on the wiki) you can see she killed her first victims, had a cool off of a week or two then killed again. This was followed by another two victims again on a one-per-day basis so in short, when it comes to those cases, timing is everything and it's also mainly about losing control over the M.O. (I suppose a short period between kills is often an indicator of it).

Hines is a great example. You're spot on there, his kills were well planned and full of ritual aspects, too much so to be a spree killer. Now it is possible to be a spree killer and still plan your crimes but not in the way that Wallace had. When you look at his list, you see he had a two week gap between his first and second kill, then three days before his third; there's your serial mark. Then the rest of the time, there was NO breathing space in between. I have to agree with what Rock said. Hines is hands down one of the best examples of this kind of unsub on the show.

Hope this helps clear it up for you, Diego.
