I think you are asking for too much information for something they obviously don't want known. How about just the last drop date so we can see if has dropped since the most recent patch?
All that info would be nice but it would be included for every item in the database. That seems excessive. Image, debris dropped 198,321,287,927 times last month, the target drop rate can be as high as 140% on some hulks, last drop 0.00217 millisecond ago.
