Yes, me too.
I think in part it is just the very different ways people seem to vote - some voters seem to place greater weight on personal taste and enjoyment of the style, others seem to give more weight to the perceived 'production quality', still others seem to be seeking a balance between these factors, each in their own way.
Sometimes it can be a little shocking to see the different perceived value expressed in a number from 1-5
I love it when people share thier voting criteria, I think that is of great value to those of us interested in such things ...but I totally understand why there is no requirement to do so and how this works well enough with people just doing what they see fit with no explanation required!
