@ -16,7 +16,7 @@ For split keyboards using soft serial, the computed WPM score will be available
| `WPM_ALLOW_COUNT_REGRESSION` | _Not defined_ | If defined allows the WPM to be decreased when hitting Delete or Backspace |
| `WPM_UNFILTERED` | _Not defined_ | If undefined (the default), WPM values will be smoothed to avoid sudden changes in value |
| `WPM_SAMPLE_SECONDS` | `5` | This defines how many seconds of typing to average, when calculating WPM |
| `WPM_SAMPLE_PERIODS` | `50` | This defines how many sampling periods to use when calculating WPM |
| `WPM_SAMPLE_PERIODS` | `25` | This defines how many sampling periods to use when calculating WPM |
| `WPM_LAUNCH_CONTROL` | _Not defined_ | If defined, WPM values will be calculated using partial buffers when typing begins |
'WPM_UNFILTERED' is potentially useful if you're filtering data in some other way (and also because it reduces the code required for the WPM feature), or if reducing measurement latency to a minimum is important for you.
