JUDGESREPORT

Shows how the band as a whole rang when ringing in a given position or following other bells. When ringing in a given position shows for example whether the band is weak at lead or whether they are habitually late at backstroke in last place. For following other bells, shows how the band as a whole is affected by bells other than the one each is ringing. Might indicate "fear of the bells", or perhaps that the band is distracted by a ringers handling style.

Shows how each bell rang. There are eight tables covering all combinations of:

- Handstroke and backstroke
- Mean (i.e. average error) and standard deviation (i.e. amount of randomness)
- Bell-after-bell and Bell-in-position

Perfect ringing would have zeros in all squares of the tables. Each square is the mean or standard deviation of multiple individual striking errors and where there are fewer than five occurrences the square is marked grey as the value may not be a statistically significant indicator of striking faults. Otherwise pink highlights negative values and orange positive values, and the darker the colour the worse the error.

If the touch contains rows with errors above the threshold the rows containing the errors are ignored for the purpose of these tables. This improves the likelihood that the dark coloured cells reflect striking faults even when there are method errors which would otherwise make the numbers meaningless. The row(s) of this touch that were ignored were: .

These graphs show the variation in speed and errors(*) over the touch. Ideally the speed should be constant, as speed changes are a source of errors since everyone in the band will not change speed in exactly the same way. However gradual changes are unlikely to be the cause of errors. Limited investigation suggests that peal speed changes of less than 1 second every 10 rows are fairly harmless and slowing down is less harmful than speeding up, which suggests that the classic conductor's shout of "Keep it going!" is probably right!

The speed graph shows the average speed as an orange horizontal line.

The errors graph shows the threshold above which HawkEar assumes the errors are due to method or ropesight errors as an orange horizontal line. The rows of the touch which above this threshold are: IGNOREDROWS. Statistics on the Report to Judges tab gives the standard deviation ignoring these rows.

This graph shows the number of errors(*) of different sizes. The peak or "median" value represents the "everything going right" capability of the band.

The shape of the histogram should be roughly that of a bell with its mouth down. However method or ropesight errors will cause the curve to be lop-sided and extended to the right. If this happens the reported Standard Deviation for the touch will also be higher than the median and the difference between the two shows the disruptive effect of such errors.

When working on improving the overall standard of striking in the band, recording the median standard deviation of each touch is a good way of monitoring overall progress.
