2 threadcounts = 1 tartan ?

[saharris]

I do apologize if I have already asked this, but if so, then I have completely forgotten the answer –

If a tartan has two pivot points then it would be able to be rendered correctly from two different threadcounts. For example, the XMTS tartan can be rendered properly from either:
• W12 DB64 N6 DB6 N2 DB6 N4 B8 DB2 Y4
• Y4 DB2 B8 N4 DB6 N2 DB6 N6 DB64 W12

Is one threadcount “preferred” over the other? If so, then by what criteria is one selected?

Thanks! (again?)
