50 minutes later, the notion of running a2l is no longer  necessary. It seems the loops have pulled the alignment together quite nicely. ETMX f1 Mode4 was rung up pretty good but is slowly ringing down as are it's counter-parts. Bounce and Roll have also diminished well below reference. Range is averaging ~ 60Mpc. Winds are ion the 20mph range.
