For those who were using steem.cool before, thank you for your patience! The update is in and the app is now attuned to the new reputation system. Special Thanks to 
For those of you who just want to skip the Mumbo Jumbo just head over to http://steem.cool enter your username (or others hehe) and be entranced by the glowing power up bar, watch as your reputation increases over time, and continuously refresh hoping you've leveled up. Otherwise continue on...
So let's start off with the new Steemit Reputation Formula
((log10(abs(reputation#))-9)9)+25
Seems pretty straight forward, right? Well that's if you're a mathematical person of course but for those of you who aren't lets break it down a bit. Still may require some mathematical know how but what can you do? ;)
First thing you should know is your Real Reputation is big giant number anywhere from 0 to 100 Quadrillion or even more (which steem.cool displays in number of billions) so a log10() is very important when getting to a much more reasonable number.
log10()
Since I'm not the best teacher... let's see how these guys explain it
Mathworks
Y = log10(X) returns the common logarithm of each element in array X. The function accepts both real and complex inputs. For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf ,Inf). For complex and negative real values of X, the log10 function returns complex values. more...
Ok lets see what Wikipedia has to say
That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication. For example, the base 10 logarithm of 1000 is 3, as 10 to the power 3 is 1000 (1000 = 10 × 10 × 10 = 103); the multiplication is repeated three times. more...
I think we may be starting to understand ;)
+25
This is used to set the minimum Rep Rank to 25, meaning when you have a reputation of 0, you don't have a rank of 0 but a rank of 25! Therefor anything under 25 would be a negative reputation, so be aware of that!
The rest of the formula is subtraction and multiplication which brings you to that good old number called your Reputation. Since here on Steemit we are all about open source so here is the formula in use broken down step by step (Along with a inverse formula I use to find how much Reputation you need to level up) Thanks again for help with this
calcReputation(value) {
reputation_level = 1;
neg = false;
if (value < 0)
neg = true;
if (value != 0) {
reputation_level = log10(abs(value));
reputation_level = max(reputation_level - 9, 0);
if (reputation_level < 0) reputation_level = 0;
if (neg) reputation_level *= -1;
reputation_level = (reputation_level*9) + 25;
} else {
return 0;
}
return reputation_level;
}
currentREPLevel = calcReputation(RealReputationNumber);
currentREPLevel = number_format(floor($currentREPLevel), 0, '.', ",");
NextRepLevel = currentREPLevel+1;
NextRepLevel -= 25;
NextRepLevel = NextRepLevel/9;
NextRepLevel += 9;
NextRepLevel = pow(10, NextRepLevel);
RepRemaining = NextRepLevel - RealReputationNumber;
percentRemaining = 100-(RepRemaining/NextRepLevel)*100;
If anyone wants me to explain this further and in more detail let me know in the comments below or pm me on steemit.chat I'll be happy to chat with you.
In the first version of steem.cool I had a Potential UpVote Rep Weight or amount of REP you could give with a single UpVote (Avg.) I excluded this for now because I have not figured out the formula for this yet. I have yet to go through the steem / steemit code fully in this respect so I didn't want to jump the gun. I personally think this is great information to have and will be working on getting it back up ASAP!
I know it has been 3 whole days since the newest Reputation System which in steemit world is quite a long time but how is everyone feeling about it? i know that this along with down voting has been a big topic lately!
Speaking of DownVotes... I am working on a tool to see how much power your DownVote (Flagging) actually has, so stay tuned for that.
Hope you enjoy getting SteemCooled! & Follow Me! for updates on this app and more AWESOME stuff!

Ps Not sure about my last tag of #steem-help , figured this could be a helpful post for users looking for more information on their Reputation... But if it is miss-categorized let me know!
