Border width for regions on a map/chart

Hi all.

I think this topic has came up in the past. After a few colors, it grows
difficult to maintain a good contrast. One way to offset that is to have a
strong border between sections, both in color and thickness. If my memory
serves me correctly, the conversation broke down after it got to 2, 5, 10,
and 10+ pixels.

Personally I am in the 5-10px range, but the individual wants a source.
