Such a slight systematic shift is usually due to a lack of datum transformation before reprojecting the data. You should test the different transformation and your data will overlap correctly. I can't tell which one is best for you based on the information provided, but you can test it relatively fast. EDIT: if this doesn't work, you have two solutions: ...

To do this I would use the Union tool to calculate the overlap relationships between polygons. I would then use arcpy.da.UpdateCursor to iterate through each polygon and add up the ranks/weights of any polygons that overlap in that area.

You could use ifelse as an alternative to if and else blocks in a function. You can nest multiple statements in an ifelse and if you are trying to vectorize a problem, it is much cleaner. Note that an absolute abs statement on a zero value still returns zero so, I just used a very small number as a constant. library(raster) x <- raster(nrows=100, ...
