Statistics
True wind statistics have been added to the T1 processor beginning revision 20.05. These functions are designed to help in decisions involving laylines, Vmc sailing and sail selection. There are six parameters displayed in round-robin order.
| Function | Example | Description |
| Wind direction | Mt:224 | The average wind direction over the last hour. |
| Trend | Tr:+5.1 | The persistent shift of wind direction over the last hour (in degrees/hr). The example reads "wind direction has trended clockwise (+) 5.1º over the last hour". |
| Shift | Sh:5.5 | The RMS wind shift (in degrees). The example reads "5º each way from mean". |
| Velocity true | Vt:12.6 | The average true wind speed over the last hour. |
| Puff | Pf:4.5 | The RMS variability in true wind speed. The example Vt and Pf together read "true wind has been 12.6 knots ±4.5 knots in the last hour". |
| Peak wind | Pk:17/15 | The highest windspeed (over a 5 second average) and how long ago it occured (in minutes) during the last hour. The example reads "highest wind was 17 knots, 15 minutes ago". |
These Shift and Puff items are statistical; there are two other functions that give the current differences in wind direction and speed from the mean (see Shift and Puff).
Error codes associated with the Statistics output are:
| 181 | Not enough data to calculate statistics. After 10 minutes of steady data, this error should go away. | ||
| 182 | No wind direction available or unstable conditions. Check your system for boatspeed, apparent wind and heading. | ||
| 183 | No tacks. Tacking is required in order to detect wind shear. |
