Hello!

I tried Critter 1.6 w32 with Multi PV = 2. Analysis by Critter 1.6 w32 in an Intel Pentium D930 (using two cores) with 512 MB of hash and 32 MB of cache for the full set of Gaviota TBs, running under Arena 2.0.1 GUI:

I stopped the analysis after 27 minutes; Arena showed five tablebase hits. Critter prefers 27.- h5 at depth 20/66 in my analysis.
