You can thank Betson for this. They were going to return all xxx numbers of games they got originally because they were all "broken." Under normal behavior, the saucer starts as weak as possible, then gets stronger and stronger until the ball leaves the eject. It then remembers that setting and will adjust it one way or the other if it needs to if something else goes batty later on. The problem was Betson was checking the games in test without ever starting an actual game, and the game doesn't adjust the strength with the door open because for all I know power could be disabled at that point, so it would be solving a non-existent problem. But, this did make the game seem broken, because the ball wouldn't leave the eject. I didn't want to compromise the learning or the top lane feed, so the solution was if the door was open, kick the ball as hard as you can to prove the frickin thing works.
Quoted from Excalabur:He got 500 in POTD a few times, but in general you don't see tournament players try to nudge for a few extra souls.
Well I wouldn't say THAT. But I would say that on Hard and Extra Hard, the soul lights don't start with any lit for 500, so it becomes much more rare. I'm pretty sure it promotes lights 100->250 before 250->500, so on multiball 3+ (on normal settings) you'd have to advance the potd 3 times before you started advancing to blinking/500 lights.
