ENGAGE_SOFT_LOOP Convergence Checker Threshold Loosened from 3.0 to 6.0
J. Kissel for S. Dwyer

As we were hovering in the ENGAGE_SOFT_LOOPS step for ~10 minutes as it creeps through the 4 spot positions in which we demand convergence of the ADS loops, we got impatient. Sheila loosened the threshold on the convergence checker for these loops (appearing on line 3032 of ISC_LOCK) from 3.0 to 6.0.
We'll see how this works for several lock stretches, and/or consider even looser thresholds on the points between initial alignment position and final position.
