What_does_this_button_do,
I got some data tables for the DC10-10 and DC10-30 from the following Flightsim website, apparently they come from aircraft ops manuals. Several other data tables for 737, L-1011 etc also available.

I found it just after reading your post so it's still active. Files are in Word or Excel format and can be downloaded.
Hope this helps.
