Yeah aware of some data quality issues in the feed, bad coordinates, missing brands, occasional obviously wrong prices. I filter out anything outside 100-300p and exclude stations flagged as closed but there's definitely still noise in there. check the methodology page for the full detail on how i clean it. On the colours, esso and shell are both red brands so they ended up close on the chart. will fix that.
