A study about my first 50 GAs won

Sorry, NO giveaway 'cause I'm low on keys and I may need 'em for an event I'm in. Put this first so you can leave if you're not interested in this without wasting more time.

Since I read somewhere of games disappearing from Steam libraries I've started a list with all the games I own.
With the passing of time this list evolved, first adding games I own outside Steam, then adding more and more info, turning what was once a simple file.txt into a full of infos spreadsheet.
I know excel is better, I keep wondering everyday if I should migrate but, as of now, the lighter, faster, browser and cloud based version of google kept the upperhand.

Anyway, I've recently added a page dedicated to the GAs I won here, to analyze and extrapolate more or less useful/interesting fact.
Here is what I've got:

• 50 GAs Received + 1 ¬Received (so, Total win = 51)

Those 50 GAs received are divided into:

• 24 Level 0+
• 12 Level 1+
• 11 Level 2+
• 03 Level 3+
• 28 were Public, 3 Group/Wishlist restricted,19 Invite only
  also 10 of them were featured GA.

The average number of entries is ~2765, and falls down to ~295 if we exclude featured GAs.
The longest interval passed between two win is ~3 months while the shortest is 5 hours.
The highest probability of win is 284,36% (yes that 100k copies of Dwarfs!?) and the lowest 0,0858% (this is also my first win, coincidence?)

• I've been level 0 for 264 days and won 8 GAs (0,0303 win per day)
• I've been level 1 for 72 days and won 10 GAs, (0,1389 win per day)
• I've been level 2 for 62 days and won 18 GAs (0,2903 win per day)
• I've been level 3 for the remaining 87 days and won 14 (0,1609 win per day)

There are also several graphs but they mostly describe what I've already written. I'll just put the one displaying the win progress over time.
