SWOLF (short for swimming and golf) is an indirect measure of efficiency. SWOLF is calculated by adding
together your time and the amount of strokes it takes you to swim a pool length. For instance, 30
seconds and 10 strokes to swim the length of a pool will equal a SWOLF score of 40. Generally, the lower
your SWOLF is for a certain distance and style, the more efficient you are.
SWOLF is highly individual, and thus should not be compared to SWOLF scores other people have swam.
It's rather a personal tool that can help you improve and fine-tune your technique, and find an optimal
efficiency for different styles.

POOL LENGTH SETTING

It's important that you choose the correct pool length, as it affects pace, distance and stroke calculation,
as well as your SWOLF score. The default lengths are 25 meters, 50 meters and 25 yards, but you can
also set it manually to a custom length. The minimum length that can be chosen is 20 meters/yards.
The chosen pool length is shown in pre-training mode. To change the pool length, press LIGHT to access
the Pool length setting and set the correct length.

OPEN WATER SWIMMING

When using the Open water swimming profile, the watch records your swim distance, time and pace,
stroke rate for freestyle as well as your route.
Freestyle is the only style that the open water swimming profile recognizes.
Pace and Distance: Your watch uses GPS to calculate pace and distance during your swim.
Stroke rate for freestyle: Your watch records your average and maximum stroke rates (how many
strokes you take per minute) for your session.
Route: Your route is recorded with GPS, and you can view it on a map after your swim in the Flow app
and web service. GPS does not work underwater, and because of this your route is filtered from GPS
data acquired when your hand is out of the water or very close to the water surface. External factors
such as water conditions and satellite positions can affect the accuracy of the GPS data, and as a result
data from the same route can vary from day to day.
