Why are the thresholds set so close to the temperature data? (Grocery)

Thresholds are positioned near the majority of the data to account for the two-hour delay in alarms, ensuring timely alerts if something goes wrong. If the thresholds are set too far from the data, an alarm might not be triggered in time to save the product. The two-hour delay prevents nuisance alarms from defrost cycles, but it also requires the thresholds to be closer to the typical temperature range.
