The following are the fields shown under the Session Summary:
1. Session type: How the session was categorized when it was created (practice, competition, etc.)
2. Players Checked-In: The number of players who have been assigned MxEncoders and whose
MxEncoders have communicated with the system.
3. Players with Impacts: The number of players who have had impacts downloaded by the system.
4. Total Impact Alerts: The total number of impacts that have resulted in alerts being sent to the pager
5. Active Players With Impact Alerts: The number of players who have communicated with the system and
who have experienced an alertable impact
6. Events Outside Of Session: The number of times that the MxEncoder was activated outside of a
defined session period
7. Download Rate: This is an indication of the average delay between impacts occurring on the field and
data being downloaded by the system. An exact number is not given, instead a time range is shown.
A range in green indicates a short delay and a range in red indicates a long delay
8. Last Sync: The date and time when your SRS laptop last sync’d with the main database
The following are the statistics shown under the Team Head Impact Exposure heading:
1. Daily Top Ten List: This is a list of the ten most severe impacts that day. The list is populated based on
the head impact severity metric you select (linear acceleration, HITsp, etc.) The selected metric is
controlled by the pull-down menu above the Top Ten List
2. Frequency: This category of session summary statistics tells you the total number of impacts a group
of your players have experienced along with the fewest number of impacts a player in that group has
experienced, the median number of impacts for that group and the largest number of impacts
experienced by a player in that group
3. Location: These statistics show you where on the helmet the impacts occurred by percentage for your
selected group of players
4. Severity: These statistics show you the median, the 95

Data Review Functions Available Using RedZone
While RedZone is your primary tool for administrating your session and roster lists, it is also where you can
create summaries of impact data over customizable time ranges and manage your SRS user settings.
Charting
Through the RedZone Charting Page (Figure 42), you can view data for team sub-groups or individual players in
a variety of charting formats: column, bar, line, area, pie and scatter. The Baseline, Time Period and Chart
Parameter fields allow you to control how impact data is organized and presented. For both the linear
acceleration histogram and impact location graphs, you can view impacts by team, offense, or defense only
(baseline data) or compare individual players and positions to the whole team, offense, or defense. In addition
to data charts, the top 10 impacts (by linear or rotational acceleration) can be listed over any desired data
range. When you have set your charting parameters click on the “Plot chart” button to generate your chart.
