What Circle of Confusion setting to use in DOFMaster?

I know there is a Sigma DSLR setting in DOFMaster but am never sure whether this is based on the  20-20 vision from a normal viewing distance standard (can't find the exact details of the standard at the moment).

So if I'm using a DPxM and want to be able to view detail close up in a print up to 30" x 20" (and have up-sized by a multiple of two in post processing if that makes any difference) what Circle of Confusion setting should I dial into DOFMaster to know what's the near focus distance etc. please?

I'm not a scientist so hpe the above makes sense of what I'm trying to achieve!

Thanks.
