Not sure which chart you are using.
Since the OP has Trojans, here is a link to the chart direct from the Trojan website. Trojan's numbers are a bit different from the commonly used chart, but not by much. I know there are other folks out there who have developed their own charts, but I will stick with a well-respected company like Trojan before I would accept a self-developed chart from an individual who has done his own research and then posted it on the internet.
Link to Trojan chart - scroll down the page to find the chart.
