The Long Term Acceptance Rate (LTAR) is a crucial metric in evaluating the performance of septic systems, particularly in determining their suitability for specific properties and soil types. The range indicative of better performance typically reflects the ability of a septic system to adequately treat and dispose of effluent over time without becoming saturated or failing.

The range of 1.1 to 1.2 indicates that the system is performing well with regards to both treatment capacity and the ability to handle effluent volume effectively. This suggests that the system can support longer-term usage without significant issues, making it viable for properties that may experience higher usage or load.

In contrast, the lower ranges, such as 0.5 - 0.7 and 0.8 - 1.0, may indicate that the system is on the borderline of acceptance and could potentially face challenges in efficiency and capacity. Higher ranges like 1.3 - 1.5 may suggest overperformance that could also lead to issues if the system is not correctly designed for such high acceptance rates.

Thus, the selection of a range from 1.1 to 1.2 as indicative of better performance aligns well with the expectations for robust and functional septic system operation over the long term.
