Estimated wins?

wow so u are a lucky guy. 2.42 with 5 wins :)I already saw a guy with over 12.0 with 0 wins

Nope.

It's just a function of how many times you've entered and how many other people you were up against.

Entering a giveaway with 10 other entries = +.1 estimated wins.
Entering a giveaway with 20 other entries = +.05 estimated wins.
etc. etc.

In theory your actual wins should be close to your estimated wins if the law of averages applies to the data set, but it's all luck based. Doesn't actually do or mean anything, just a fun little stat so you can keep track of how lucky you are.
