By having a less precise display, you increase the margin of error. Also, with the decimal points you can see if the display is still moving. Without it you may be off by as much as 1.5 %, and that's just in the reading. Any error in the sensor compounds that. Then there might be an error in the calibration if it's done with static air instead of being done at the same flow rate as the air from the scuba tank. All these errors compound each other. For this reason I usually try to err on the site of safety. This means that I use the next higher percentage for purposes of O2 toxicity, and the next lower one for purposes of N2 absorption.
