Yeah I agree they're more of a tool than interesting. With it up if you've got 2 dps doing 800dps and the third doing 550dps you need to know so you can look at improving it. It may just be an inescapable situation but it's definitely good to know. Kinda like keeping tabs on your gas mileage on your car. If it suddenly dips then there may be an issue that you need to look into before damage is done (fuel pump failing, fuel filter clogged, bad O2 sensor, etc. etc.)
