A few years ago I dove deep into that stuff and surmised that unless things are drastically off, its not that important. It helps me because sometimes my hips got so bad I was at 60-40 L/R (but that's rare).
IMO, the only one that's really beneficial is 'stand up time' but even then software doesn't support it (that I know of). For example, differentiating the power curve standing vs. sitting and optimize your sprint.
