I had seen relatives which were narrowed down to L2, Z142, L20 etc... but I suppose it's understandable because L2 (and especially those branches of L2) are more common U152 branches than Z56. I suppose this factor influences how "deep" one's "intermediate haplogroup" is.
I got a more downstream assignement at 23andMe after I had updated to the newest chip version. The chip version seems to make a difference.
