Release 2.3.0 (January 2025)

New: Selection of the units (mm, inch, mrad, degrees, etc) for all table headers (see ‘TolerancePool’ sheet).
Improved: flexibility to set the number of decimal places.
Fixed: calculation of the ‘Realistic total’ in cases where the worst-case sum is smaller than the statistical sum (non-Gaussian distributions + small number of items).
Fixed: the ‘Capability’ calculation for positive minimum specifications (e.g. a specification such as: +0.4/+0.1).
Added: an example of how to enter tolerances in the TolerancePool (see ‘Help’ sheet).
Updated: examples for all 3 types of tolerance tables in the ‘Help’ sheet.
Updated: the ‘Help’ sheet.
Fixed: minor error in the 6DOF Tolerance Table nominal values.
Other minor improvements.

Improvements in the text of the Help Sheet.
Removed the data for the examples in the TolerancePool, SPC-TolerancePool and the VectorPool.
Further detailed example in the Help sheet.
Added an ‘Integration’ sheet, explaining how to integrate this template into another.

Correction of some failure rate formulas in the ‘SPC Tolerance Chain’ sheet;
Added a missing translation in the ‘SPC Tolerance Chain’ sheet;
The direction of the nominal value (‘1’ or ‘-1’) and the selection of the distribution type are only visible if applicable.

Added: language selection;
Added: 0 to the nominal dimension summation type to indicate that it should not be added.

New: separate summation of the standard deviations and the deviation from the mean;
New: calculation of the Cpk of the sum instead of the capability. ‘Old’ calculation of the capability is still present;
Updated: calculation of the estimated failure rate (due to the above changes);
