I've been combing the faq, and watched the EV vid, but I'm still confused on how the Luck adjusted winnings work for sngs.
How is it calculated exactly? Say it's a $10 husng. If I have 2500 vs someone that has 500 chips, and we have had no show down. We get all-in for a 50% flip and they win. Chip stacks are now 2000:1000. We get all-in for another flip and lose again.
Stacks are 1000:2000, and we lose another flip. Our winnings are $0. What are our luck adjusted winnings? $5? More?

$10 husng -->50% flip--> it works something like this
1500 vs 1500 chips:.
You win the SNG 50% of the time--> and your equity will be $20 (EV Diff = -$10) but 50% of the time you lose and your equity is $0. (EV Diff = +$10)
You Luck Adjusted Winnings will be the SUM of all the EV Diffs + your final equity.
Your final equity will be either $20 (if you win) or $0 (if you lose)
So in this example (1500 vs 1500 chips) the luck adjusted winnings will always be +$10 (no matter if you win or lose)
----
2500 vs 1500 chips:
This time you win the SNG 50% of the time--> and your equity will be $20
but 50% of the time you lose and you will have 2000 chips and your opponent will have 1000 chips.
1500 chips are worth $10 in equity, so when you lose the hand your equity will be $13.33
So your EV is 50% * $20 + 50% * $13.33 = $16.66
Therefore if you WIN the hand--> and your equity is $20 (the EV Diff will be -$3.33) and if you LOSE--> your equity will be $13.33 (EV Diff = +$3.33)
2000 vs 1000 chips:
If you win your equity is +$20 (EV Diff = -$6.66)
If you lose your equity is $6.66 (EV Diff = +$6.66)
1000 vs 2000 chips:
If you win your equity is $13.33 (and the game is NOT over)
If you lose your equity is $0 (EV Diff +$6.66)
So losing 3 coinflips in a ROW-->
2500-500 (1)-->2000-1000 (2)-->1000-2000 (3)-> Your Luck Adjusted Winnings will be: $3.33 + $6.66 + $6.66 = +$16.66
