ReadiScore = your personal fatigue rating
So far, we’ve talked about the dangers of fatigue and how it can be rated by looking at how much you sleep (quantity), how well you sleep (quality), and how consistent your sleep schedule is.
If our system now has three days of sleep information from you, it has calculated your Score for today.
70, 80, 90: what the scores mean
Studies show a direct relationship between the ReadiScore and the likelihood of causing an accident. A high score means you’re well rested. However, as scores decrease, fatigue and associated safety risks increase.
Remember when we mentioned fatigue has similar effects to alcohol?
ReadiScores have been linked to Blood Alcohol Concentration (BAC) readings from a breathalyzer. Specifically, a score of 70 compares to a 0.08 BAC reading.
If you sleep reasonably well and normally at night, your ReadiScores may fluctuate from the mid-80s to low 90s. However, if you sometimes work nights, your score could fall well below 70.
Using your ReadiScore to improve your daily fatigue risk awareness
Understanding your daily fatigue risk helps to paint a clearer picture of how your sleep impacts your safety. You can always view your current Score and the time at which you may hit a high risk level (i.e. a Score of 70 or lower) on the main screen of the app.
But, the details are where you'll really be able to increase your fatigue risk awareness.
Your ReadiScore will naturally change over time. By dragging your finger across the graph, you can see it change, along with your fatigue risk.
Transitioning between day and night shifts can also cause your ReadiScore to change a lot, which has an impact when you're comparing your ReadiScore on the Performance tab.
You can set work hours on the Risk tab to monitor your fatigue risk and the changes to your ReadiScore at a glance. You can choose to save the work hours you enter so you can see them overlaid every time you access the Risk tab.
Once your work hours are set, you'll see it overlaid on the graph. At the top of the screen, you'll see your fatigue risk indicator and the associated colors (green, yellow, red) on your work hours (if and when they apply).
Note: If you're working at night, you may see a large dip in your ReadiScore after midnight. This is because a "new day" has started in the average ReadiScore calculation and you haven't slept yet.
Review: what influences the ReadiScore
Your score is directly informed by the quantity and quality of your sleep, as well as how consistently you go to sleep and wake daily. In other words, good sleep habits, sustained over time, will result in a higher score.
Other factors that affect your alertness
The ReadiScore is based on how much or how little sleep you get. But, there are many other factors that affect your alertness it can’t account for such as: the use of stimulants, medication, or other underlying health issues.
