Question Engine throttling limits - RS-68, RD-180 etc.

[Wishbone]

Are there any hard data/links on the subject? The only stuff that I have memorized by heart concerns the SSME, would like to know the lowest throttle settings about other engines, too. (It won't be too hard to make a DLL preventing the player from violating the limits, BTW).

Well, some may not regard Wikipedia as the most reliable source, but it gives 58% to 101% for the RS-68, and 40% to 100% for the RD-180.

A DLL preventing users from going outside the limits of an engine(s) would be nice. Could be applied to engine restarts as well- this is the case with Kulch's Space Tugs.

EDIT:
Astronautix gives a lower-bound throttle setting for the RD-180 of 50% (see here).
