Default Hot Idle Compensator When Adjusting Idle

Hi,
I have a question that until recently I never really paid much attention to.

In the Pontiac Service Manual it says to depress the Hot Idle Compensator while adjusting the idle.

Now, Ive never done this and would like to know if it is something that should be done.

I know Tom Vaught's answer already "engineers do things for a reason" ha ha

Thanks,
Don
