When you say Bob-ABP-Timestamp, I assume you're still referring to the row-key? If so, I'm confused as to what the column name would be.
Or, are you saying that each row should be a combination of the patient name and timestamp, with the physiologic parameter name as the column name? Would that still provide better query times when only looking for a particular patient's data?
