How small is too small-box pleated Black watch

[WClarkB]

Your wisdom is requested.

I have some very heavy 18 oz double wide BW which is enough to make a knife pleated kilt or two. I was thinking that, persuaded by Matt Newsome's arguments, a 4 yrd box-pleated kilt would be a good summer wear addition, lighter but enough Substance to Swish (STS parameter). The material is indeed beautiful.

Having never pleated to stripe I was anxious to do that. Splits are 21.5 / 19.5 and 21.5/22.5. The sett is 5 3/8" (136mm) and if I go one a sett (ie strip) then I get 12 pleats but only 45 mm wide (less than 2 inches by 6 mm). If I go to the recommended method: 1.5 setts I get 8 pleats of 2+ inchs per pleat and the pattern "approximates" the sett.

MY QUESTION:
how important is the "no pleating less than 2 inches" rule for the box pleat?
8 large pleats sounds unattractive compared to twelve smaller ones. This is my 3rd kilt.
