  displays include:

Nominal Place

  • your bell number(s) high-lighted in the changes,
  • your nominal place as input, and the target place,
  • the mat(s) high-lighted in the animation window,
  • the count of method errors and your percentage accuracy in the status bar,
Nominal Places Display

Screen Shot 1:

  shows the mat, highlight and status, recording an error
where the user, ringing the 2, forgot it was minor and stayed in 5th's place.
Also shown, dimly (not so clearly here for red or blue), is the row ahead.

Striking Precision

  as shown below
  • high-lighted bell number(s) in strike positions in the changes listing,
  • your striking accuracy, as a percentage of a strike, beside the row in the changes listing,
  • the relative position of every strike, in the striking monitor, either a single bell or all bells,
  • the number of strikes in selected ranges in the striking monitor,
  • the averages of all blows, plus early and late blows, in the striking monitor,
  • a graphic striking report with the record/playback facility and
  • fault assessment, for either an individual or the whole band, in the striking report.

Striking Precision Monitoring

In addition to the place, displays include the following:

Changes Window

Highlighting in the listing can be either All of the ringers' bells in their actual striking positions, or the bell in the entered place, depending on the selected mode.

  The Changes window

Striking Monitor

The striking monitor is in a separate window and has three modes.   It can be resized to improve its impact and visibility across the ringing chamber.   With a single ringer's bell, the Striking Monitor shows your striking faults, expressed as a percentage of a strike (early/late), for the latest hand and back strokes, in either Single Bell, All Bells or Averages mode.

Single Bell mode

  displays the ringer's bell in its correct position (including in method) within the range +/- a whole blow (inter-strike interval).   With perfect striking the bell will appear in the centre, but will shift to left or right (early/late) and the colour will change from green, through yellow, to red, and disappear altogether, as the striking deteriorates.

Accuracy is shown at the bottom as a percentage of a strike, early or late, for each of the latest hand and back strokes, and above that is the Striking Range Hits count - see below.

Screen Shot 3

  shows the 2 is 37% late at hand stroke.
Striking Monitor - Single Bell mode

All Bells mode

  shows all the bells in their actual strike positions, in the colours of the Changes window.

Screen Shot 4

  shows the 2 is 37% late at hand stroke.
Striking Monitor - All Bells mode

Averages mode

  shows the average position of the ringer's striking, All strikes and averages separately for the Early blows and Late blows, indicating the trend and the range.   The colours range from black for values within +/-10% of a strike (interstrike interval), then green, graduating through yellow and orange to red at +/-100% or more.

Combi (added with v12.32) is probably the most useful: the average of the early and late faults combined: (Abs(Early) + Late) / TotRows.

This is designed to allow occasional reference to check for improvements, discouraging users from intensively viewing the display as with other modes, leaving them free to concentrate on listening.

Screen Shot 5

  shows the Averages display.
Striking Monitor - Averages mode

Striking Range Hits Count

The Striking Monitor also counts the number of ringer's bell strikes within each range, as shown near the bottom of the window, with optional tighter ranges for experts.   They can be re-initialised after your striking has settled down, and the results can be saved to file for future reference, or for use in a spread sheet.   The panel is shown in all modes with a single ringer's bell.
