Some Frequently Asked Questions About GreyMatterStats


What is GreyMatterStats?

GreyMatterStats is a free service that provides our users access to a wealth of sports handicapping information. We currently provide data for professional football, college football, professional basketball, college basketball and major league baseball.

Are you a Tout Service?

While we do project the outcomes of games as part of our overall analysis, we are not a tout service, selling picks. At times throughout a season, as certain statistical trends or angles come to our attention, we will point them out in our Blog, Twitter, FaceBook, or in emails we send to registered users, but we will never recommend specific selections.

How did all this get started? 

This venture started out as a hobby, many years ago, where we collected data each season and would look for statistical advantages, trends, and angles.

Recently, we took a hard look at the countless sites that offered information on sports handicapping.  What we found was, that while there are some really good sites, and some really bad ones, there didn’t seem to exist a single place that,

a)     truly provided the serious sports handicapper with one stop shopping for information tailored specifically to statistics


b)    that allowed the user to ask their own “what-if” questions.

Our goal was to build a website rich with content, presented in a concise, user-friendly format.

We didn’t want our site littered with terms such as Chi-Square or Standard Deviation that while informative to some, would be useless to the masses.  Instead we crunch the numbers in the background and present the user with the data in terms of simple percentages and differences that indicate a history of outcomes in an endless number of situations.

We hope that we have done our job, and that a sophisticated user will find the depth of what we have to offer as meaningful as the guy who wants to click on a graph and think…Graph…Green….Good.


How many years of history do you display?

The database focuses on four time frames when displaying information;

Current Season – which represents data for the current season updated through the most recent results

Previous Season – which represents data for the previous season including playoffs

Current 30 Days – which represents data for the Current 30 Days

All History – which represents a cumulative rolling multi-year history (the number of years varies by league) including any current season to date information

We feel that presenting the information in this fashion gives our users a unique look at what is happening currently, what has happened in the recent past, and how that compares to trends over time.

How do you calculate Projected scores?

Our system weighs many game-specific factors when projecting scores, such as historic home field advantage, statistically how the offenses and defenses match up, and our own strength of schedule calculation.

It is important to note, that Projected scores are simply ONE tool to use when doing your Homework.  Use the Projected score in conjunction with the wealth of other tools at your disposal to either make a case for or against a particular game.

Why are some games missing?

The only occurrences of what one might perceive as “missing data” should be the when a Team played a game for which there was no Line, or generally accepted Line.  For instance, if a Division I college Team was to play a Division I-AA, then for the purposes of our archive and system, that game never occurred.

Over the years as our database was built, we made sure to have data keyed and verified to ensure the validity.  Prior to us launching this site, we contracted to hand check large samples to insure the greatest accuracy possible.

We are confident in the integrity of our archived data, but if we should find an error or anomaly, it will be corrected immediately and all history updated to reflect any changes.

How do you project data early in a season?

Most handicappers know you have to be careful early in any season, for a number of reasons.

From our system’s perspective, we utilize a blend of historic data in projecting outcomes early in a season. Then we slowly wean off of the history, and lean more and more on current season data.

It’s a balancing act and our approach is different for football, basketball, and baseball.

For the first game of a new season for any Team, the prior year’s final statistics are displayed for informational purposes, but as soon as a Team has current season statistics, those will be displayed.

Why do your early season rankings look so off?

The ranking is an overall team rank that is derived via an algorithm that weights the quality of wins/losses in conjunction with overall statistical performance across several key indicators.

Obviously, as more data becomes available throughout the course of a season, more credence can be placed in the rankings.

What is all the color coding about?

When looking at so much information on a screen, it’s easy for things to get lost, so we adopted the convention of color coding certain data types as follows:


Green – A Team either is or was the Favorite in a particular game; Or a displayed data element indicates a Favorite


Red – A Team either is or was the Underdog in a particular game; Or a displayed data element indicates an Underdog


Orange – A result is or was Over the Total in a particular game: Or a displayed data element indicates Over


Light Blue – A result is or was Under the Total in a particular game; Or a displayed data element indicates Under


Gold – A result is or was a Push in a particular game; Or a displayed data element indicates a Push

Caution Indicator

Caution Yellow – Indicates a unique situation such as Teams playing a particular game at a neutral site


Light Green – A Win against the Money Line or Line in a particular game; Or a displayed data element indicates a Win


Light Red – A Loss against the Money Line or Line in a particular game; Or a displayed data element indicates a Loss


How often is your system updated?

For football, you should expect a new week of data to be online by 12:00pm EST on each Tuesday of the football season, through all playoff rounds. A new week of data for football is defined as any game to be played from Tuesday through Monday of the current time frame. Throughout the week, as Lines move, or other pertinent information changes or becomes available, we will of course be refreshing the data.

For basketball and baseball, in which games are played daily, the data will be updated as it becomes available. For instance, if on a Wednesday, data is available for the current day as well as for Thursday, the next day, the system will display information for both days.  Again, as Lines move or other pertinent information changes or becomes available, we will of course be refreshing the data.

If a game is currently “Off The Board” at the time of an update, the system will display a message indicating such and you will not be able to view the information on that game.  Once the system recognizes that a game that was “Off The Board” is active again, the data will be refreshed and available for viewing.

As the system is updated throughout the day, you may see the following message.



If you do encounter this message, please wait a minute or so for the update to complete, then hit refresh (F5)on your web browser  to see the most current information.

What Lines do you use?

We are licensed to receive and use data from a well-known real-time sports information provider.  Via our data feed, we utilize current specific consensus Money Lines, Lines, and Totals when updating our database, as well as other variable information provided to us as part of our licensee agreement.

I have a suggestion regarding something that I would like to see on your site, would you consider that?

Honestly, we would love to hear from you. If you feel we are missing something that the handicapping public would find useful please feel free to reach out to us and tell us what you think. If it makes sense to us and is achievable within the constraints of our database system we would be happy to add your suggestions.
