i guess you missed my point a bit:
whichever integrator you're using, it will have to deal with your data, which, as you said yourself, is messy...
hence, as john d'errico usually says at this point: garbage in, garbage out... no matter what box is in between...

however, there are many other ML integrators available, see roger stafford's reply...
