Percentage at flop

I don't use a poker odds calculator while playing, but occasionally I like to use one the next day to see what the odds had been in certain situations. As I may have mentioned, I've written a calculator of my own so I can customize it as I see fit. As it turns out, the calculator on the PokerStars site doesn't provide a way to calculate the heads up odds at the flop when the opponent's hand is unknown, so that's one of the customizations I've done. I call these odds the percentage at flop odds. The more traditional case of the heads up odds at the flop when the opponent's hand is known I call the heads up flop odds.

Last night, I lost a bunch of chips on the following hand (opponent screen names have been removed):

Seat 1: (11200 in chips)
Seat 2: (32600 in chips)
Seat 4: (52800 in chips)
Seat 5: (5800 in chips)
Seat 6: (42600 in chips)

My calculator tells me my percentage at flop odds of winning were 94.54%, but my heads up flop odds were only 69.29%. It's lucky for me Seat 1 only had $11K in chips at the start of the hand, or it's likely I would have hit the felt. I had some good luck after this hand, winning a pot worth $30K with a king high flush, and a pot worth $17K with a pair of kings.

During current Hold'em session you were dealt 32 hands and saw flop:
- 4 out of 5 times while in big blind (80%)
- 3 out of 5 times while in small blind (60%)
- 15 out of 22 times in other positions (68%)
- a total of 22 out of 32 (68%)
Pots won at showdown - 3 of 6 (50%)
Pots won without showdown - 2

delta: $2,800
