"weighted average"

[illunious]

Would someone please explain what weighted averages are (re: the PT gametime window).

[Ed Miller]

An EV equation is a weighted average. It is your average result, weighted by the probability of each result occuring. Say you make a bet that has a 60% chance of winning $1, a 20% chance of winning $5, and a 20% chance of losing $10. Your EV is:

EV = 0.60 * 1 + 0.20 * 5 + 0.20 * -10

You are averaging 1, 5, and -10... weighting each term by its probability of occuring.

Suppose you have 2 players, A and B. In the Game Time window, vp$ip is calculated like this:

weighted average vp$ip=
(vp$ip(A)*#hands(A)+vp$ip(B)*#hands(B))/(#hands(A)+#hands(B))

where

vp$ip(A) is player A's vp$ip percentage
#hands(A) is the number of hands for player A
and similarly for player B
