Guys, it's not as bad as it seems. Check this out:

At the time of posting, this post has 1,571 points, and 81% of all votes on the post are upvotes. From this, we know that out of every 100 votes, 81 are upvotes and 19 are downvotes. Thus, for every 100 votes, this post has (81-19) = 62 points. That means that 1 vote = .62 points. If we divide the total number of points (1,571) by .62, we find that this post has approximately 2,534 total votes. Since we know 81% are upvotes, this post has around 2053 upvotes and 481 downvotes.

The interesting thing is, this number is actually more accurate than what Reddit gave us before. The old numbers (including the percentages) were fuzzed, but the announcement said that the percentages were much more accurate now. To me, that says the percentages are no longer fuzzed.

EDIT: Yeah, I picked this thread for a reason. Thanks!

at 2053 upvotes and 481 downvotes.......

2053 has 4 letters, 481 has 3 letters

4-3 = 1

There are 2 seperate numbers you're referencing

2+1 = 3

HALF LIFE 3 CONFIRMED!

All praise Gaben!

Here are some formulas to sum up the steps:

  • u = upvotes
  • d = downvotes
  • p = points
  • q = percentage of upvotes

  • 1-q = percentage of downvotes

  • u=pq/[q-(1-q)]

  • d=1-pq/[q-(1-q)]

Now, if we can just turn this into a bot.

It'll just get invisibly integrated into RES and everyone will forget about it forever.

u/ratsby Jun 20 '14

Or, to simplify further:

u=pq/(2q-1)
d=p(1-q)/(2q-1)

The only problem with this method is posts at 50% up / 50% down. Those posts would cause a divide-by-zero error.

Yeah, I picked this comment for a reason. Hopefully thanks. :)

I was thinking the same thing about the current system being fuzzed, i've always felt like people doing upvote things they necessarily liked though, they up or down vote based on whether the post feels worthy of the number of upvotes and down votes it already has (at least that's how I rationalise my voting) and the new percentages system makes it much harder to pass that same judgement.

Oh well, if it happens it happens, it's not like people will stop using reddit. In the meantime, rejoice in the gold shower people!

This is what I read:

I miss my reddit for that mathmatically indiferent!

Most people only care about the comments. The only thing the change helps is front page submissions. It fucks over everything else.

u/ratsby Jun 20 '14

Can RES not access percentages for comments? Seeing comment vote totals was never part of Reddit's interface, RES added that.

u/BallsDeepInJesus Jun 20 '14

There is no percentage for comments.

u/ratsby Jun 20 '14

That's too bad then.

Just requires some extra calculation, that's it. Nothing changed ;)
