There is half step and then there is half step...:-) Not all half steps are created equal, and you are probably seeing that. Half step that utilizes the pole points, ie one phase on one phase off and both phases on 100% will be different than half step that utilizes 70.7% for both phases on. Then you have halfstep that doesn't use pole points like your 100% phase - 41% phase which will give you different results yet.
