SGP/EBBR/E22 - Incorrect averaging interval at E22

On November 9, 1993 version 4 of the EBBR program installed at Cordell, OK
(E22) was mistakenly modified in one area during the process of modifying a
calibration in another part of the program.  The mistaken modification was
a change in the execution interval from 30 seconds to 10 seconds.  This
modification remained in the program until November 22, 1993 when it was
discovered and changed back to a 30 second execution interval.  The
modification produced no ill effects as the execution interval only
changes sampling and averaging periods.  A 10 second execution interval
results in three times as many samples being taken, which, when averaged,
should actually produce more accurate results.  Therefore, data quality was
not affected.  This PIF was written only to document the fact that the
mistaken modification was made, and when it was made.
