this morning DLM has increased the applied interleaving
I cant see where any actual DLM changes have been made. Your DLM profile is still INP=3. Interleave delay = 8ms
If you mean Interleave depth, although the value has changed, it wont make any difference to your performance. Using INP=3, the modem calculates the sufficient error protection required to be able to recover from noise burst of 3 DMT symbols. DMT symbols (bits carried in the bin) can vary depending on your sync speed - the higher the sync speed then the more DMT symbols.
Your sync speed has increased from 39192 -> 43845. Thus depth has increased 767 -> 859. If you look on MDWS, there is a direct correlation between your increased sync speed and interleave depth.
