I think that what you're trying to say here is that neither you nor
your program are good enough to _see_ the compensation. After the
line white is winning.

An example continuation is Nc4 Qf4 Nb2 Bxh7 Kxh7 Ng5+ Kg6 h4

Does movei see here that white is won?

a) It's not because your program is not smart enough to solve the positions
that they're incorrect. They may not all be correct, but your claim that
some of them are incorrect just because your program doesn't solve them is
by far one of the most ludicrous I have ever seen here.

b) If you don't have the right knowledge, more time will help very little
in a pure positional set.

c) Some of the positions included are insanely hard. This is why I
said that you shouldn't take the test too serious. I think all positional
testsuites are bull, but that doesn't mean you can't have fun with them.
