Quick question MJ — what about changing the formula for User Power to something like:
Likes / sqrt(Posts)
Here’s the idea… we want a rating that takes into account both the QUALITY of contributions (that’s the ratio of likes to posts), AND the QUANTITY, in a single number.
If we have two users as follows:
U1: 100 likes, 2 posts
U2: 10000, 200 posts
Then the current formula says their User Power is equal, ie 50.
But intuitively we know this isn’t quite right, since the quantity of contributions isn’t taken into account.
The new formula takes it into account — it gives 70 U1 and 707 U2, which imo is much more accurate and reflective of both the QUALITY of their contribution AND the QUANTITY.
The way I came up with the formula is by reintroducing the quantity of likes by multiplying L/P * L. Then took the root of it to normalize it, leading to:
So here’s a few examples:
Kak — 8,992P 41,094L — 4.57 Current
MJ — 35,918P 150,591L — 4.19 Current
Andy — 16,252P 59,588L — 3.67 Current
Myself — 1,497P 4,063L — 2.71 current
Fox — 3,550P 23,945L — 6.74 current
BizyDad — 1,986P 6,689L — 3.37 current
If we order those from high to low, we get Fox, Kak, MJ, Andy, Bizy, Myself.
Here’s with the new formula:
Kak — 433
MJ — 795
Andy — 467
Myself — 105
Fox — 401
Bizy — 150
So the order becomes: MJ (the KING haha!), Andy, Kak, Fox, Bizy, Myself.
I feel this last order is a MUCH better reflection of contributions.
What do you think?
Good work. And not because I ranked higher.
Yea, I have to take a deeper dive into this but it seems more mathematically accurate. There might be an issue as Xenforo template language likely won't accept a Square Root in the equation.
