Slic3r: Confusing tool tip advice

I've been working with Slic3r for a few weeks now, and am really enjoying the control it gives me over the Prusa printer. However, I've run into problems interpreting some of the tool tips in some settings:

It looks like there are 4 options:

1. Set the parameter to a non-zero value to set an explicit width.
2. Set it to a percentage, in which case it will be applied to layer height.
3. Set it to zero, to use the default extrusion width.
4. "Otherwise" 1.1.25 X nozzle height will be used.

My question is what to enter into the setting to get the "otherwise" setting applied. I can obviously calculate these values myself. I'd like to use one Print Settings profile for all my nozzle widths to avoid re-creating multiple profiles when swapping new nozzles in. I'm getting decent prints using everything set to 0, but for many of these parameters, I'd like to use the "otherwise" option.

Edit: After trying with these settings all "0" or all blank, it looks like the "otherwise" settings is used, at least according to the comments in the generated gcode files.

Re: Slic3r: Confusing tool tip advice

There are only three options.

1. Set the parameter to a non-zero value to set an explicit width.
2. Set it to a percentage, in which case it will be applied to layer height.
3. Set it to zero, to use the default extrusion width. If default extrusion width is not set (= otherwise) 1.125 layer height will be used.

Is that clearer?

If Default Extrusion Width = 0 AND External Perimeter = 0 then 1.125 * nozzle width will be used.

Ah, OK. That makes some sense, and does seem to match the resulting gcode. If you care enough to enter a default width, presumably you'll either use that or care enough to also tweak the other values. Go all default, and it makes a sensible calculation.
