An example test station running in a JACE-202 Express was found to fit this unsuitable category. This station had 176 COV histories, each writing every 5 seconds, along with other NRIO components and BACnet components (making little additional history usage). SRAM support in this station resulted in an ongoing automatic save approximately every 6 minutes—about a magnitude away from ideal.

176 COV histories changing every 5 seconds yields 126,720 changes/hour (176 * 12/min * 60 min/hr).
