Correct idd, going to plot the curves of timing vs rpm and current to see if I can spot a point where inefficiency really gets a lot worse.
Why I asked the question was that idd, I read and always hear the guys with an analyser always talk about the magic 6A or more recently idd 3-4A setting.

If running the analyser at 1S will obviously result in lower current while freewheeling. So I was wondering if I had to compensate for that so it'll pull 3-4A at 1S.

That being said, my motors in 1/12th usually run fairly cold and I havent found a way to get some temperature in them. Throw on too much gearing and the car becomes sluggish at the timing I mostly use (50-55 degrees). Maybe I need to try a lower timing and gear a lot higher (driving on a moderately large, flowing track at this moment).
