The ratio of 4 bets to the total pot is 64% because:
(Note that we want to know what percentage of the opponent's 4 bets is of the total pot. So, from the opponent's point of view, we must calculate the total pot)
According to the formula, the total pot is: 3 times the opponent's bet + the amount of the pot before the opponent's bet
(here, since we are counting from the point of view of 4 bettors, so we are the opponent and we had raised to $100)
(Actually, we did not raise 100 dollars, first we called 40 dollars and then raise 60 dollars. So our raise is 60 dollars)
(60*3) + 40 + 40 + 80 = 160 + 180 = 340 is the total pot
Now he has 4-bet $220, so 220 divided by 340 is 64%
That means he has 4-bet 64% of the pot.
--------------------------------------------------------------
Our pot odds are also 1 to 2.7 or 27%. Because:
$80 was in the pot + opponent raised $40 + (we called him $40 and then raised $60) + (opponent called us $60 and then raised $160)
as a result:
The total pot is 440 and we have to call 160 dollars. It means 160 to 440 or 1 to 2.7 which is 27%
What is your opinion? Are my calculations wrong?
