Go with the size frame that fits you best regardles of the label on the bike. Some have medium and medium-large and large and others have different amounts of reach depending on the intended use of the bike and so there are categories of bikes being sold by Trek and Specialized and other companies. It is more complicated than in the past when everything was based on the length of the seat tube.
You posture and riding position is what is important and if you cannot extend your arms properly or feel scrunched up or need to stretch to reach the controls on the handlebar then this should govern your selection and not some chart.
