The first plot here shows the range integrand for LLO's 65 Mpc lock on March 6th, our March 16th 15 Mpc lock and Monday's 28 Mpc lock.  The second plot shows the cumulative range difference as a function of frequency between these locks.

The green line on the second plot shows that the 12 Mpc we gained between March 16th and is mainly due to the improvements from 20-100 Mpc, (mainly due to ESD low passes and decreased MICH contamination of DARM).  

The blue line shows where we need to improve to catch up with LLO in inspiral range  There are 25 Mpc to be had in the 20-40 Hz region.  

These plots are made using an old script by Grant Meadors,  and data that Dan managed to get for LLO.
