I took some of the suggestions here about increasing tension, and ratcheted it up a little bit.
Per the Park spreadsheet:
DS avg: 135
std dev: 11
NDS avg: 76
std dev: 13
Here's what that looks like:
Using the visualization tool made it pretty easy to tighten up the range, to:
DS avg: 139
std dev: 7
NDS avg: 78
std dev: 7
And here's what that looks like:
I think it's time to put the rubber on the road and see how it holds up and maybe fine tune after a couple of rides. I am a little worried that the tension is pretty high (DS avg of 139Kgf), but we'll see.
Thanks to everyone for the tips, suggestions, and education in this thread and my other recent threads on related wheel topics. I feel a lot more confident about tearing down and rebuilding a wheel.
