- for something like GTT, they just want to see one graph, of the data points (the glucose values), but each data point needs to know what the patient state way (post fast or whatever) - for sports medicine (as an example) they want to see two graphs, the heartrate versus the treadmill speed/inclination, or somesuch. The latter therefore can be most easily modelled in 2 separeate HISTORYs, whereas the first is modelled as one, with each EVENT carrying a patient state indicator. - thomas beale
