Proportional luck

Hi all,
would you like to share what is your luck on Steamgifts?

The luck score means whether you won more or less than the expected amount of games based on the final odds of all the giveaways you joined. For example, if you joined 10 giveaways with 5 participants each, you have 1/5 chance to win per giveaway, so your expected amount of wins is 10*1/5 = 2. If you actually won 3 of those giveaways, your luck is +1, if you won 1, your luck is -1. Steamgifts reports your overall luck score at https://www.steamgifts.com/stats/personal/community , e.g. as "Overall, you've been unlucky, and won 4 fewer gifts than estimated since you first joined."

I think that the basic luck statistic is interesting but it is even better to discuss it as a proportion of the expected wins. So I propose that we could discuss "Proportional Luck", which is the proportion of wins you have lost due to bad luck or the proportion of extra wins you have gained due to good luck. Proportional luck computed as follows:

Proportional Luck = Luck / Expected Wins = Luck / (Current Wins - Luck)

So for example, I have currently won 38 gifts, and my luck is "4 fewer gifts" (Luck = -4). Therefore my expected wins were 38 + 4 = 42, and my Proportional Luck = -4 / 42 = -9.5 %. That is, I have lost nearly 10% of my expected wins due to bad luck.
