Just realized that question not about math itself, but regarding settings handling.

In your case better to express width in percentage: set it 100% to explicitly make it to be deducted from the nozzle size.

Seems like setting it to 0 exposes some bug in configuration.

Yes, your determination is correct, when you set the default width to 0, the width is 0.45mm. But when I set it to 100% it shows 0.40mm.

@SoftFever Is this a bug?

0 means automatic or default in this case. When you put a absolute non zero value or percentage, Orca will calculate it accordingly
