The DLM will attempt to give you the best speeds it thinks your line, while still remaining stable and within thresholds, can receive based on the data it collects.
I would consider having an Amber status on the Dynamic Line Management (DLM) system to be OK, or in other words stable but not outstanding enough to warrant any positive changes (or corrective changes if outstandingly bad). As long as your MTBE (which consists of ES and SES) is at or above 30 (since your ISP is on the Speed DLM profile) - so one error in the form of ES or SES every 30 or more seconds on average - then your speed or latency should never be negatively impacted. Since your current error rate is five times lower than that (MTBE of 150 when I averaged your totals), you have a healthy margin and should not see much lower speeds (while crosstalk and other interference factors may reduce the available spectrum available, any further changes should not be from the DLM itself but other external factors unless it impacts the MTBE).
Since the monitoring period for the DLM is from 00:00 to 23:59:59, if you experience a very high burst of errors during this timeframe that exceeds the thresholds then you can anticipate changes the next day that may reduce your sync speed (such as banding) and increase latency (such as interleaving). Although the interleaving tends to not to be applied on lines that have G.INP support from the Cabinet since the latter has a lesser overhead and nil impact on latency.
In order to see improvements on your line, you would need to attain or exceed an MTBE or 300 to have a Green status. Having a Green status just means that the DLM will make changes to remove any banding, interleaving (if it was applied before) and lower the noise margin.
