CV question (a bit of math)

Ssssh, quiet! It is in those percents of cents that the super moderators use a kickback scheme to become filthy rich using SteamGifts! But if you point that out, they will instantaneously send a secret a---

It is all good now. I am having a great day, what about you? We are fine. Carry on.

Cheers!

Reduced Value means that only 15% of the current Steam price will count towards your contributor value (CV).
You will get $0.75 each to the CV for the first 5 copies.

After you give away a game 5 times, it will decrease in the CV.

The CV is decreased by 10% for each additional copy.
In this case, you decide to give away 50 copies of a $4.99 Reduced Value game, it would add $10.44 to your CV.

Maths?

there is a dev giveaway with 50copies ending and the dude gave away 11 copys before
looking after his stats later should answer your question
or look for ended giveaways with like 5k-10k copies and look if your math checked out .

I think only cg can tell you how numbers are rounded in the db.

Interesting. The way I would implement it I would probably internally store a higher precision (with proper rounding if my precision is not enough) for each GA then add all the high precision numbers.
That way even your first entry would be off, 4.9915%=0.7485, 50.7485=3.7425...

But this is just the "what I would do", I have no idea how CG implemented it and I don't really expect you will be getting an answer here

I found a user who have ever gifted only one game (thousands of copies). And SG says that he or she reached the theoretical maximum of 14x game's CV with an accuracy of 0.01 level (that corresponds to 0.5 CV since his or her level is 3). This means SG uses high enough precision arithmetic so that rounding does not affect the final result.
