I don't think the positions above show anything that is impressive. The Baron solves all of those, except for WAC230, within a few seconds. In WAC163 it announces mate in 11 in 18 seconds (P4-2.4), but already selected the key move much earlier (<8 sec). Btw, I'm not contesting that Ktulu 7 is strong. It proved that in matches against the Baron (e.g. by Günther Simon). These examples just do not prove anything (rather the contrary). Richard.
