Default Slide Theory, Carb Models, and Jetting

Looking for peoples settings and the slides they are running, along with the carb model. This is a bit of a continuation of GMPs findings in his 2012 model, along with some info from another forum where 2 x 36mm carbs have reported good results using the JD Blue and a 40 pilot. One has a 6.5 notched slide, unsure on the other.

My particular bike required the idle to be turned in all the way with the stock F diameter needle and a 40 pilot just to substain something that you could barely call an idle. After trying all combinations, a 40 pilot and W diameter gives the best idle, which doesn't hang, and only lightly burbles off load. Going richer to a H diameter needle I get more burble and only slightly more torque. This is all with a non notched #7 slide in an 38mm ASII carb.

You'd imagine the smaller 36mm ASII would prefer leaner jetting due to an increased air velocity, along with the richer slide, so it has me wondering, does the notch make that much difference??? or are their other variables at work.
