I have been present at one as a kid that got out of hand pretty badly (if there was actual decent wind that day, could have been epicly bad) and was actually part of another at a job site that was edging that way before we took an active hand at fire control. As in we actually had to use what we were thinking of our "emergency" measures.
From my own perspective it would be the number of effective people on hand that would limit the size of my fires moving forward. The steps above from others are also key of course. With the circle devoid of any and all living things around it being paramount. The one that nearly got out of our hands IME there was one that was cut but not nearly large enough. Lesson learned there.
In other words if it were just me or maybe one other, I would burn it in smaller batches. It would be more time consuming of course but much easier to handle. Plus, can rid the piles of animals that may have moved in. That one I saw as a kid, a deer and her fawn were sheltering inside when it was fired and no one realized. The deer made it out. The fawn did not. I will never forget that little shriveled corpse. Still feel like **** about it to this day even though I had not real role in it.
It's probably an overabundance of caution to break it up into smaller burns but I will be damned to the lowest circles of hell before I let myself start a multi county brush fire.
ETA: I am also taking notes here. Good stuff suggested above. Especially THIS from Gunny456 above:

This is gospel from what I have seen with my own eyes. It goes from everyone watching and feeling good to everyone scrambling with the "oh *****" fear in their eyes in just seconds. Do not hesitate to call it in and do not be afraid to do so.
