SuperClass & SubClass

I notice that I get different results on
tap server & panic server.  Is that strictly
due to having more explicit links on the panic
server KB, or is there some software change?

Explicitly, I get more results from

    subject isa ?;
    subject isc ?;

Note that subject isa ?; expands to

    subject isu ?;  <=> GetData subject type no
    subject iss ?;  <=> GetData subject subClassOf no

and subject isc ?; expands to

    subject isp ?;  <=> GetData subject type yes
    subject isg ?;  <=> GetData subject subClassOf yes
