No, I wasn't aware of this tool, and it showed me why I wasn't getting the promotions I expected. Now I think I should see better results. Last nights run was in something less than an hour, whereas the night before had many more compressed DLE's which took 4:45 to complete. The mix of compressed vs why waste the time trying straight copies is confusing the issue, but I don't recall a just over 40 minute run in recent history either. We'll let this "settle" for a couple weeks and see.
