[S] Acting on low DOE confidence

Can anyone assure me that I'm not just playing the lottery when I act on
low statical confidence from DOE's performed on manufacturing processes
at work.

My take on this is that if I don't have any idea which way to turn the
knob so as to produce the best product then I might as well go with the
direction pointed by DOE's even if it is lower than 50% confidence. So
far it's worked out fine but I afraid someone is going to pin me on it.

Since confidence lower than 50% worked, does this mean that confidence
was low just due to confounding or poor selection of factor ranges or
does it mean I was lucky? Does 50% confidence really mean a 50/50
situation in this case?
