Make the pattern with the strings at tension. Measure the speaking lengths 
with the strings at tension.

If the bass termination is a capo bar, after rubbing the strings for 
placement, remove the strings and make a rubbing of the capo.
Mark the termination point on the capo by running a line or straight edge 
from the bridge pin through the rubbing to the capo.
Measuring the string lengths off the pattern in this instance, it is easier.
