Dojo questions.

Most of the recent sub-9 times in GAZED have been from hackers. It is possible legitimately but you need very good control and have perfect timing (and cap 100%, obviously).

For the timing, Dojo has a 10 second spawn interval, so what I do is keep a clock that shows seconds up next to the MapleStory window and when I'm going into the last floor for a round (i.e floor 5 where Zombie Mushmom is) I'd look at my clock and make a mental note of when it spawns (for example, let's say it spawns at x:50, so I need to remember the 0). So in order to get the boss to spawn instantly, I need to be in the next map a second or two before 0 so I don't miss the spawn at 0. You can sit in the waiting areas as long as you'd like so use this to your advantage to time the spawns.

Nearly every action in this game goes by an internal maple-time which starts actions in the 10 second interval. Mined something? You have to wait for the 10 second interval to reset. Monsters spawn? 10 second interval(in some cases bosses will not adhere). Pink bean spawning starts it's actions in the 10 second interval. Cooldowns, although not entirely true, are slightly persuaded by this interval.
This game has a strong connection to this interval, which is all i'm really trying to point out.
