NetSol drops?

[hosting3.com]

Any idea when NetSol usually drops domains with:

Domain not found locally, but Registry points back to local DB.
Local WHOIS DB must be out of date.

thx

They usually drop 5, sometimes 6, days after the message without registrant appears. However, there are names that I track that changed to that status months ago, and they still have not dropped.
