A Glut of Petroleum Products

i didn't know that either, and I don't think it is correct, see bottom of tonto.eia.doe.gov/dnav... . So stocks seem to be based on compulsory surveys with a response rate of 98-100%. Now that still leaves the possibility that these respondents themselves model rather than measure the stocks, but that is unlikely, as it is simply easier for a refinery/port/etc to read their meters rather than devise a model. dieuwer, if you have any other serious info, please provide.
