The California chart states "Fewer than 5 persons out of 100 will exceed these values". The article you linked contains charts from the Texas ABC which do not indicate what percentile they measure. The original source [1] is a dead link but it's still available in the Wayback machine [2], where the PDF states "Note: The figures are averages and may vary based on the amount of food in your stomach." The difference in these charts in no way "implies that at least one source is lying via statistics", just that you are attempting to compare different statistics dealing with something that's going to be quite variable from individual to individual. IMO, the 95th percentile is a better approach, if your intention is to give people a rough intuition for how much might be too much.
