Chasosaur,
I'm glad you dug up my posts from the other thread and incorporated them in your rulesheet. This weekend I was planning on taking the glass off and getting specific point values as you progress through Rescue and Emerald City multiball.
I completed EC multiball (collected all three gifts from the wizard) this morning, and I feel that each gift was worth 25k, 50k, then 75k. I'll confirm over the weekend and post what I find.
I also know that Rescue has some pretty sophisticated scoring. Super jackpot at the castle scoop becomes available once you collect three jackpots on at least one of the six jackpot shots. The inserts for each jackpot change from green (single JP) to yellow (double JP) to red (triple JP) to show that you have 3, 2, or 1 jackpot(s) left. The insert is blue once you've completed that shot, and is worth a few points, but less than a single JP. Then you go up to the castle mini-playfield, bash down the door, and collect the super. I know the super is tied to the value of the jackpots you've collected. Once you collect a super all of the jackpots reset on the lower playfied. I'm pretty sure the value of the jackpots is tied to how many balls you started rescue multiball with (starting with 5 balls is worth more than starting Rescue with 2 balls) I also think the value of the super can be multiplied if you hit the rescue letters before collecting the super.
So, those are just some observations I've noted, and will try to confirm over the weekend. Maybe someone else has already figured it out, but I haven't seen it posted anywhere.
