Hi everyone, hope you're all well.

I'm trying to make sure I am comfortable with these two calculations and they seems slightly different and I think I've only just spotted it.

On one of the quizes I was completing there was a situation where, with a pot size of 3575 we are facing a bet of 1600 and I was looking at calculating how often we need to be correct to call.

"It's pot odds = bet/(bet + pot) = 1600/(1600 + 5175) = ~24%"

So in this case, the denominator includes the bet twice, once because it is the bet and once because it is part of the pot. So this gives 1600/6775 which is approx 24%

Different from that is the MDF calculation which, as I understand it (and as it shown in today's 30 day challenge video):

1 - (bet / (bet + pot))

in Jonathan's example he is looking where there is a bet of 8 into a pot of 10 and then calculates through to get:

1 - (8 / (8 + 10)) = approx 55%

If we apply that calculation to the numbers from the first example:

1 - ( 1600 / ( 1600 + 3575)) = approx 69%

So that is to say, facing a bet of 1600 into a pot of 3575 our minimum defence frequency is 55% and when we call we need to be right around 24% of the time. The minimum defence frequency can be more because it can include raises (either as a bluff or for value) and the 24% we need to be right to call is also an absolute minimum so the numbers don't HAVE to match.

Am I thinking about these correctly? TIA
