I'm trying to get finer decimal ratings (for half star or finer ratings like 4.5, 4.9, etc), too, but I'm not clear on the instructions for how to do this so far. I've made a column called ratings and set it to floating point as described. But then what? I just have an empty column now, how do I get the data from the ratings column into the decimal column? Where is the decimal rating behind the graphical stars located? Is there actual decimal data with the built in metadata download or do I need some plugin to actually grab the raw ratings again from Amazon?
