Stable income: Somewhat stable

Based on research and online sources, pool routes can provide a moderately stable income for individuals. While there may be fluctuations due to factors like seasonality or unexpected repairs, many people are able to consistently earn from managing pool routes. If your best friend quit their job to pursue pool routes full-time, it would be a moderate risk but with potential for stable earnings. I'd rate it a 3 out of 5 because while there is a decent baseline of income, occasional variables can impact consistency.
