Looking at top prize 6, it took an abnormal length of time to award the prize but they made up for it by having prize 7 awarded very soon thereafter.

Well, those are the book print gap between the previous prizes above. With that huge gap between #2 and #3, we can assume a $1M prize went missing somewhere. Also, it is worth noting that the $1M and $4M prizes on this game both appear at roughly 1 in every 3 million tickets and that a book of this game comes with 50 tickets. So, it should be roughly every 60k books but we know the math doesn't work out that perfectly with larger and smaller gaps to meet or get close to what the average is supposed to be over the span of a game.
