> Partial data will serve as a distraction if you present it as important. If you ascribe to the importance of its display, then you are allowing it to be a distraction as an observer of the display. But, yes, in practice I agree that most humans are foolish and will allow it to serve as a distraction. > I'm saying this doesn't belong on a dashboard. Granted, they just did this for fun. Maybe or maybe not. There are definitely good reasons for removing it from the dashboard. I agree that it is not presented well. Outright permanent removal of the vague notion and concept of this particular data and its relevancy is a different matter. Exploring alternative presentations, getting more sensors and more relevant data, etc. (This is of course stating the obvious.) But I'm not really commenting on that at this time. > The more data the better - That's not true. Some data is better than others. Some data is poor quality. Some is unimportant. This is often debated with vigor on both sides (okay, there's actually a gradient of n-dimensional in-betweens, not explicit sides) of the argument. (Collect it all and figure out relevancy from analysis, then scale back data collection where it was determined to be irrelevant. Be presumptuous based on experience and collect only what you believe is relevant. Expand and contract collection periodically as something in-between. The list goes on and on and on and on of possible configurations and approaches.) Of course some data is better than others. Some data is more relevant than other data for a given operational context. And, yes of course, besides just relevancy, fundamental things like accuracy, precision, and error are all aspects of data collection and analysis. But, back on topic, both sides of the argument have merit. The reality is, like all things in life, there is a pragmatic balance point. (Not necessarily a point, though. In reality, usually an n-dimensional volume, but that's another topic.)
