Make a comparison

1. In Session Overview, choose rate and power. Add GPS pace or heart rate if recorded.
2. Zoom the part of the row you want to compare. Use the group controls below the curves to create a named group from the visible strokes.
3. Open Boat & Oar → Averaged curves. Select that group and another group or piece.
4. Switch to Individual strokes to inspect the strokes behind an average.

Searching the stroke table only filters that table. Create a group when you want a new selection to determine the averages.

Choose metrics and curves

Advanced is the default detail level and includes all Core choices. Choose Core for a shorter list. Choices stay grouped by Oar, Boat, GPS, Time and Body; changing the detail filter preserves your selected plots.

Choose bend, moment or estimated handle force for the load display. GPS speed and GPS pace are separate choices, as are peak moment and peak handle force. Use Show variability to add stroke-to-stroke spread to supported averaged curves.

Boat metrics include set, pitch, heave, distance check, speed check and energy-loss check. See the metric reference for their meanings and inputs.

Read and adjust the curves

• Time or sweep angle: time shows when events occur; sweep angle shows where they occur along the stroke.
• Full-cycle context: the default time view spans 1.5 cycles, including a quarter-cycle before catch and after the next catch. This shows the transitions between recovery and drive.
• Horizontal sweep angle: select it under Oar at Advanced level. It combines the two supported horizontal gyro sweeps. Oar depth angle is also available.
• Scale and position: adjust each curve’s range and vertical position. Use Auto for the relevant visible data, All for a broader range or Fit this stroke for a closer view.
• Hover: read each curve’s value in its own units. The shared time or angle appears at the bottom of the cursor line.

Horizontal sweep joins smoothly through late recovery where the next catch is recorded. This display adjustment preserves drive values and workout metrics. Missing neighbouring data remains a gap.

Curve heights are independently scaled. Use the labels and units when comparing magnitudes.

Arrange and play the animation

Use Layout for side by side, animation above curves, curves above animation, animation only or curves only. Curve and animation views use the same stroke selection.

Click a curve to make the animation follow the pointer. Click again or press Escape to freeze it. Adjust the viewing angle, zoom and water display; use 1× motion exaggeration to judge the size of movement.

For a sequence, open Individual strokes, choose the piece, group or range, and press Play selected strokes with Continue through selected strokes enabled. Turn continuation off to repeat one stroke. Recorded gaps remain gaps.

The standalone combined replay also has a stroke navigator, a fixed-centre cursor option and a Visible strokes control for up to six cycles. Individual context uses retained neighbouring strokes; averaged context repeats the selected average.

The animation is a model built from the available data and geometry. A displayed opposite oar may be mirrored from one recording. Read boat motion and replay for the hull reference, waterline and slip.

Use the GPS map

The map can show a selected group or the strokes visible in Session Overview. Choose a metric to colour the route, then zoom or pan. The track and available pace or speed depend on the GPS recording.

Map backgrounds need internet access. GPS speed is speed over ground, so current can affect it. Gaps in the recording remain gaps.

Save a view and reuse it

1. Arrange the plots, metrics, scales, layout, map controls and animation camera as you want them.
2. Open Setups, enter a name and choose Save new. Use Update selected to replace an existing setup.
3. Choose Make default to open this report with that setup in this browser.
4. Choose Download setup to keep the small .ritmo-setup.json file.
5. In another workout’s report, choose Setups → Import setup and select the file.

A setup carries the display preferences, including curve choices, summary and table selections, separate average and individual scales, layout, animation camera, zoom and viewing angles. Map display controls carry over; the new workout keeps its own route and map location.

Importing a setup preserves the new workout’s data, oar side and selected strokes. It skips unavailable metrics and tells you what could not be applied. Workout names, recorded samples and sensor alignment are excluded.

Local setups can restore selections within the same workout. Use Back up all to keep a copy of your saved setup collection. Keep the downloaded JSON to use your preferences in another browser or on another device.

Understand averages

Server-generated group and piece curves use the analytical samples. Strokes are compared at matching elapsed times or sweep positions, so the number of contributing strokes can change along a curve.

Groups created in the browser use the individual curves stored in that HTML. Their curves can be less detailed when the report contains reduced samples; their metric summaries use the stored analytical values. Show variability describes differences between strokes.

Distance check, speed check and energy-loss check summaries are the arithmetic mean of valid member-stroke values. They are not summed. Missing values are excluded, rather than counted as zero.

Export and re-analyze

• Summary and averaged-curve CSVs: export the selected comparison.
• All Strokes CSV: export the columns you have chosen.
• Shown-curves CSV: export the selected individual curves and units.
• PNG or JPEG: save the current plot and legend.
• Download animation HTML: keep a standalone replay of selected content.

A report calibration change rescales supported load and effort values while preserving the original detection and grouping. Re-analyze on the server to change processing settings or recalculate an older workout. A downloaded HTML keeps the data and controls of the version that generated it.
