USER GUIDE FOR REAL PLAYER RATING INTERACTIVE TOOL
The Quest for the Ring Toolbox is the only known place on the internet where anyone can rate players by entering game or season performance measurements.
TO USE THE REAL PLAYER RATING TOOL
1. Click "Add" A form will pop up allowing you to enter player numbers. DO NOT enter numbers in the view mode, which is the mode that you see when you arrive on this page. You must click Add and use the pop-up form.
2. Enter the performance measures shown for the player.
3. Click "submit"
4. Refresh this page. The Real Player Rating and the Real Player Producton for the player should now appear, along with all of the numbers you entered.
5. Repeat 1 through 4 for more players or more teams.
USE THE TOOL FOR ANY TIME FRAME YOU NEED
Provided you have the correct statistics, you can look at a player's performance for an individual game, for his or her entire career, or for anything in between, such as a season.
USE OF THE TOOL TO COMPARE TEAMS
You can also use the tool to rate and compare entire teams, simply by using the combined measures for all the players. Suppose you have two teams in a League that were considered extremely close, and they play in the Champiionship, and the Championship is decided in overtime. In such a case you might not be convinced that the team that won the Championship was really the better team. To investigate, you could compare the team RPRs of the two teams to try to get at which was really and truly the better team.
One interesting idea for Team RPR is to use combined team RPR (the sum of the player RPRs) to compare the same team from one year to another, which would go a long way towards answering a question that everyone asks all the time but that often no one ever has a very good answer for: which team was better: last year's or this year's?

BASE VERSUS ADJUSTED REAL PLAYER RATINGS
The tool here technically shows Base Real Player Rating (BRPR). This is already an extremely useful measure. But when Quest for the Ring reports team or NBA Real Player Ratings (RPRs) it reports them adjusted for "hidden defending".
On the other hand, Quest uses BRPR for Ultimate Game Breakdowns for individual games. It appears to be impossible to validly quantify hidden defending for individual games. With sample sizes of more than 300 minutes and especially for samples sizes in excess of 600 minutes, it is possible, under basic Statistical Smapling Theory, to come up with statistically valid estimations of hidden defending of players. Quest for the Ring has accomplished this as of very early 2009, and RPRs for teams and for the NBA as a whole are reported out only after the hidden defending adjustment has been included. Quest for the Ring is the only known site which as achieved this capability.
The root issue is that only defensive actions tracked by scorekeepers are counted in Base RPR, which is calculated in the above tool. Hidden defending is not included in the tool simply because it is impossible to quantify validly.
Such defending includes such things as man to man defending, defensive recognition, defensive rotation, pick and roll defending, defensive intensity, and defensive aggressiveness.
AN APPROXIMATE WAY TO ADD HIDDEN DEFENDING TO BASE REAL PLAYER RATINGS
There is an inexact but valid thing you can do to add the value of hidden defending into base RPR. Experience has taught that the value of hidden defending has a maximum theoretical range of 0 to ..280 expressed in terms of the Real Player Rating. The vast majority of players will fall into the range of ..040 at the low end to .240 at the high end. At the most, about 5% of players will be below .040 and another 5% will be above .240.
So what you can do is simply use your best judgement about how good a player is at defending not counting defensive rebounds, steals, blocks, and personal fouls, which are already counted in base RPR.
Theoretically, a player who never changes any shots from makes to misses would have a hidden defending rating of as low as .000. But even the "worst defensive players" in terms of "made them miss" defending, via untracked actions, will generally have hidden defending ratings of between about .040 and .060. Exactly in the middle players in terms of hidden defending will have hidden defending ratings of between .130 to .150. And the best defensive players in terms of hidden d3fending will generally have hidden defending ratings of between .220 and .240, although the absolute best such players can theoretically deserve a rating of up to .280.
AVOID BIAS WHEN ESTIMATING HIDDEN DEFENDING
I can not stress enough that when you add an amount for hidden defending to the base Real Player Rating, you are evaluating players based on defending actions other than defensive rebounding, steals, blocks, and personal fouls. Specifically, for example, when you estimate how good a player's hidden defending is, do not be biased either for or against players who make a lot of defensive rebounds.
Ironically though, players who make a large number of defensive rebounds and blocks often have lower hidden defending ratings than do "defensive specialists" who do not make a truly large number of defensive rebounds and blocks. This makes sense insofar as that it is not automatic or all that easy for players to be extremely good at rebounding and blocking and for example man to man defending at the same time. To some extent, with defending it is an either/or proposition. Great defenders can be either great rebounders and blockers, or alternatively they can be great man to man defenders and defensive recognizers and rotators.
Of course, there can be other combinations. For example, there will also be players who are average in rebounding and a little above average in man to man defending. It's just that it would be rare for a player to be an outstanding rebounder, blocker, and man to man defender all at the same time.
AVOID ALL OTHER BIASES WHEN ESTIMATING HIDDEN DEFENDING
And obviously, you should avoid bias for or against good offensive players. Quite honestly, how well or how bad a spcific player is on offense has almost nothing to do with how well or bad that player is on defense, allthough broadly speaking across the whole universe of players there is some degree of correlation.
