Finishing ai3 gives you this much score (assuming max hp = 100).
HP | Score |
0-9 | 10 |
10-19 | 11 |
20-29 | 12 |
30-39 | 13 |
40-49 | 14 |
50-59 | 15 |
60-69 | 16 |
70-79 | 17 |
80-89 | 18 |
90-99 | 19 |
100 | 35 |
So basically 10 + (current hp)/10 rounded down unless you get EM.
Finishing with 0 hp is actually possible with Voodoo Doll.

is calculated the same way, im fairly certain, so we should be able to calculate a formula to tell us the score if we know the electrum and vice versa.....

Now how should that relate to ttw is the question? How can we take that information, and say without a doubt, that a deck is better to farm with even though it isnt quite as fast?
EPG:TTW Ratio-Determining A Decks Efficiency IndexThe Ultimate Speed EM Deck
Electrum: 1690, Wins: 50, Ems: 34, Losses: 0, Avg ttw: 6.66
1690/50=33.8=EPG
33.8/6.66=5.075=EI
V2--Fire Tweaked to Max Speed
Electrum: 925, Wins: 50, Ems: 1, Losses: 0, Avg ttw: 5.24
925/50=18.5=EPG
18.5/5.14=3.60=EI
So even though The Ultimate Speed EM Deck is slower, it is a lot more efficient than V2--Fire Tweaked to Max Speed, and thus, should be preferred.
The Spins do throw a wrench into this if going for

, however, AI3 is meant mainly for score so this should hardly matter. If you do want to take them into account though, you must know how many games before V2 has a 1-up on EM.
Im having a brain stop right now though, so if someone could calculate that for me it would be great

Also note, Im not considering any of this to be new. It is all new to me, and at the very least, I have never seen it all calculated out.
