I chose the name of the parameter based on the vaguely similar parameter in the conservative governor, but the documentation that was referenced (about it only applying at top speed and the comment about skipping evaluation opportunities when it is active) was written by me in reference to the ondemand governor. It could be that someone backported some of the ondemand sampling_down_factor's behavior to the conservative governor.

Thanks for the information.
I would agree about the use of conservative, but I think that I'm not
