Understanding HeadCoach™ Metrics & Graphs
HeadCoach™ looks at your recent swim and highlights key insights based on the Objective you set in the app, and your swimming behaviour.
The Types of Metrics
There are two types of metrics you will see:
-
Average Metric
An average metric is just reporting the average for that metric for that swim, based on all the lengths in that swim for which that metric is present. For example, if you swim 10 lengths of freestyle, your FORM Score for that swim would be the average of the FORM Score you achieved in each of those 10 lengths.
-
Consistency Metric
A consistency metric measures how that metric changes from length-to-length during your intervals. Ideally, you want to hold the value steady within your intervals, and not let it drop as you become more fatigued. Holding your technique, especially during the last lengths of your intervals, will ensure you keep these metrics up.
Click on the metrics below to learn more about what they mean and how they are calculated.
| Metric name | Type | Definition |
| FORM Score | Average & Consistency | See more information here. |
| DPS (Distance per stroke) | Average & Consistency | DPS is the average distance you travel with each stroke. |
| Stroke Rate | Consistency | Stroke rate is a measure of how many strokes you take per minute (SPM). Each arm rotation is one stroke. |
| Head Pitch | Average & Consistency | See more information here. |
| Peak Head Roll | Average & Consistency | See more information here. |
| Time-To-Neutral | Average & Consistency | See more information here. |
| Interval Pacing | Average | See more information here. |
| Set Pacing | Average | See more information here. |
Reading Your Graphs
Consistency Metrics
In these types of graphs, the points represent your metric (e.g. stroke rate, FORM score etc) on each length of the intervals you did.
The green line on the graph shows your trend for this swim, while the dotted line represents your average for the last five swims.
The steeper the line drops, the more your metric has fallen between lengths in your intervals. Keep it as flat as possible for consistent performance from length to length.
Average Metrics
The graph for Average metrics shows your last swim in green and your most recent eligible* swims in grey. The dotted line is your previous five swim average.
*Eligible swims would be swims that are comparable to the current swim. For example, some considerations would be pool size and stroke type.
Understanding the Filters
For all the metrics mentioned above, HeadCoach™ may focus on a specific area only, or on all intervals of your swim. This will be noted underneath the name of the metric. You can find a list of the definitions of each below:
| Filter | Explanation |
| General (based on your swimming overall) | |
| All intervals | This indicates that HeadCoach™ evaluated all of your swimming data in order to provide feedback. |
| Speed (based on the percentage you are away from your overall average pace) | |
| Low-speed intervals | Slower than your average pace by 5% or more. E.g. for an average pace of 2:00/100, Low-speed is slower than 2:06/100. |
| Medium-speed intervals | Between your average pace + 5%, and your average pace - 5%. E.g. for an average pace of 2:00/100, Medium-speed is between 1:54 and 2:06/100. |
| High-speed intervals | Faster than your average pace - 5%. E.g. for a 2:00/100 average pace, High-speed is faster than 1:54/100. |
| Intensity (based on the values found in your Heart Rate Training Zones) | |
| Low-intensity intervals | Your Zone 1 and Zone 2 heart rate zones in beats per minute (eg. 0-133)* |
| Medium-intensity intervals | Your Zone 3 heart rate zone (eg. 134-152)* |
| High-intensity intervals | Your Zone 4 and Zone 5 heart rate zones (153-Max)* |
| *Note: If you are not using Smart Swim 2 or a compatible heart monitor with Smart Swim 1, HeadCoach™ will instead base your intensity on your speed in the same way listed above. | |
| Interval Distance (grouped together based on the total length of each interval) | |
| Short-distance | Intervals that are 150 m/yds or shorter. |
| Mid-distance | Intervals that are between 150-400 m/yds. |
| Long-distance | Intervals that are longer than 400 m/yds. |
