Steam quality/Hartford Loop

Have a 70HP watertube heating boiler, 15PSIG steam, gas-fired, low fire/high fire burner, 2-pipe gravity return system. Steam quality is 91% at low fire and 81% at high fire. A suggestion is made that adding a Hartford Loop will improve steam quality to 95%+. It doesn't make sense to me. Has anyone else run into this situation and did the Hartford Loop improve matters?

    Can't see...

    why adding a Hartford Loop -- which is entirely in the return or equalizer system -- would have any effect.  However, in the process of doing so it might be possible to improve the header layout, which might help.
