getloadavg - get system load averages
SYNOPSIS
#define _BSD_SOURCE /* See feature_test_macros(7) */
#include <stdlib.h>
int getloadavg(double loadavg[], int nelem);
DESCRIPTION
The getloadavg() function returns the number of processes in the system run queue averaged over various periods of time. Up to nelem sam-
ples are retrieved and assigned to successive elements of loadavg[]. The system imposes a maximum of 3 samples, representing averages over
the last 1, 5, and 15 minutes, respectively.
RETURN VALUE
If the load average was unobtainable, -1 is returned; otherwise, the number of samples actually retrieved is returned.
VERSIONS
This function is available in glibc since version 2.2.
CONFORMING TO

getloadavg - get system load averages
SYNOPSIS
#include <sys/loadavg.h>
int getloadavg(double loadavg[], int nelem);
DESCRIPTION
The getloadavg() function returns the number of processes in the system run queue averaged over various periods of time. Up to nelem sam-
ples are retrieved and assigned to successive elements of loadavg[]. The system imposes a maximum of 3 samples, representing averages over
the last 1, 5, and 15 minutes, respectively. The LOADAVG_1MIN, LOADAVG_5MIN, and LOADAVG_15MIN indices, defined in <sys/loadavg.h>, can be
used to extract the data from the appropriate element of the loadavg[] array.
RETURN VALUES
Upon successful completion, the number of samples actually retrieved is returned. If the load average was unobtainable, -1 is returned and
errno is set to indicate the error.
ERRORS
The getloadavg() function will fail if:
EINVAL The number of elements specified is less than 0.
USAGE
If the caller is in a non-global zone and the pools facility is active, the behavior of getloadavg() is equivalent to that of pset_getload-
avg(3C) called with psetid set to PS_MYID.

Hi everyone,
Has anyone figured out yet how to do pivot table averages using AWK. I didn't see anything with regards to doing averages.
For example, suppose you have the following table with various individuals and their scores in round1 and round2:
