There was a post about the advantage of the one game lead, but while it looked correct it didnt address this particular issue...What does moving to a 7 game playoff with a one game lead for the higher seed mean?
Here are the numbers (sorry if the formatting sucks) assuming that the team with the one game lead has an X% chance of winning an individual game:
Proability of winning........Probability of winning...........Probability of winning
one game.......................... 5 game series ...................7 game series
.30 .35 .26
.33 .40 .31
.40 .52 .46
.45 .61 .56
.50 .69 .66
.55 .76 .74
.60 .82 .82
.66 .88 .89
.70 .92 .93
The difference isnt as large as most would expect, particularly when the "better team" is the higher seed. Even a 40:60 dog in an individual game only loses 6% more of his matches (and goes from a slight favorite to a slight dog for the series).
The edge itself is as big as expected though...instead of being 50/50 to win a series that starts out even and teams of equal ability, the team with the one game lead jumps to a 2:1 favorite in a 7 game series.
