There is a lot of apples to oranges here...
For example, the depiction of functional HH hang length and WB cut length..... Point in fact, most HH ( Exped, BULA, HL, ELR) are all 100 inch ridge lines and WBBB is 101 inches.
If you decide to standardize on ridgeline length or normal ridgeline approximation, the JRB BMBH should be 9ft 3 inches, the distance between the primary rings....Width varies from 56-34 inches.
If you want to make the chart more useful I recommend adding a number of fields to capture characteristics...bug net, removable bug net, fixed bug net, top loader, side loader, bottom loader, pad pocket/double bottom, personal gear pocket/shelf etc....
As the old saying goes, "The Devil is in the details".
