I wrongly dropped the below, using Isight, but the drop appears wrong.
However, if I was operating pre-Axelishly, using my own knowledge
and experience, I would have dropped anyway.
So maybe my claim for compensation should be denied. Before I used
Isight, my thinking would be this:
"A pure 4 roll vs 4 roll position is a slim take. It's close to what we have here, but is it better or worse? I have some ugly gaps and I'm a pip down. I'll pass." I wouldn't know the EPC, but even if I did, it wouldn't
seem like take territory.

BTW, I do make fun non-financial bets sometimes. They work like this:
The winner of the bet picks a pdf or URL available online
that is interesting to the winner, and the loser of the bet is obligated to read the material.
Thus, if you win enough bets, you force other people to read up on stuff
that you're interested in, which I think is quite rewarding.

Just to explore what you might get with the (abandonned, because much
worse than the real Isight method) EPC approximation from my article
(page 20):

EPC(X) = 20 + 5 + 2*1 + 1*1 + 1*3 - 1 = 30 (exact 30.86)
EPC(O) = 21 + 5 + 2*0 + 1*2 + 1*4 - 0 = 32 (exact 31.94)

Point of last take is:

30 + 30/8.167 - 3 = 30.67 < 32 => Drop

Even with exact EPCs, the point of last take is:

30.86 + 30.86/8.167 - 3 = 31.67 < 31.94 => Drop

That's how it goes ...

The only way anyone can understand that this is a take is if they can somehow realise that the winning probability for the roller is < 78%.
Since it's quite a lot less --- approx 75%, I would expect Stick and his friends to
correctly take.
