I run pods and open 4-2-1, which I'm sure have a far greater effect on 1/4 - 3/4 throttle, but I was just saying I'm suprised he would have to increase his slows that much but did not have to raise his needles. - but I also see he's back to stock...
I'm not saying he should, just struck me as odd, that's all. Whatever the plugs say goes!!
Also, the accel pump is for quick twists of the throttle. I'f you're holding your throttle at a constant, say, half, the accel pump is not "squirting" the whole time, just at first. - that is my understanding... Hold your throttle there and watch the pump jet things. I belive it is the needle position that controls your mixture in that range.
