I've done a quick spreadsheet which looks at all the permutaions of 6-13 (i.e. 8*8*8*8) and assumes there are only 4 of each rank. However a trick I've used (see 6 6 7 6 where there's a tie) is to divide the 96 ways to get it, so each of the winners have 48 wins each. This is why the total includes 2/3 as there can be 3-way ties.
I haven't checked anything but it shouldn't take long to knock up a similar spreadsheet.

We're pretty close, but not quite in agreement. Probably something to do with the ties. My figures are the page I linked to.

I'm pretty sure the error is on my end, but I can't find it.

I found it. Stupid mistake, as usual. I definitely owe you a beer for this one.
Updated table.
