The results may be not important for you or for me but they are not nonsense
results without any value.

They have a value for the people who are interested in them.
They may be interesting for people who analyze specific type of positions when
sacrifices work(engines sometimes play wrong sacrifice and if the target was to
get some estimate for the analytical playing strength of the engines then they
could give also positions when the target is to avoid some wrong sacrifices that
part of the engines play).

Of course it is only an estimate and it is possible that you get misleading
results in specific positions when the program lose the right solution and later
find it again but it takes more than 20 minutes to lose the right solution if
your hardware is not fast enough.

We can hope that it does not happen in a lot of cases and every engine has only
small number of positions when it happens.
