225 Slant needs a good idle. what rpms are you spinning?

maybe there's no drag on the engine, because there is little frictional losses on his engine. I'm just saying, if the engine WANTS to idle lower than some arbitrary number, say 700, does it really NEED to be sped up to this arbitrary speed? I imagine the idle speed specs are an average recommended speed, taking into account fresh oem engines. Maybe his engine is an outlier, and doesn't require 700rpm idle speed.
