If you are measuring 14/15/14, then use DB14. If 15/16/15, then use DB15.
You'll be clamping the thin section is each case.
Typically when using SS14, I get tension to the point such such that two lines fall between 80 and 75. However, I'll have one line a tad closer to 80 while the other is a tad further from 75. This is what I consider to be @110 kgf which is my goal on rear drive side.
Point being is...you're allowed to estimate.
I find the Wheelsmith tool quicker to work with - while the Park version has a more comprehensive, broken out and detailed chart with a little more resolution.
The Wheelsmith tool is 10X sturdier too - I practically get a heart attack any time the Park tool ponders the edge of a table.
