Henning,
you should also check & report b.capacity(), i.e.,
b.count();
b.capacity();
b.info().reverse().like("batBuns").like("size").print();
b.batsize();
b.batdsksize();
var c := b.copy();
c.count();
c.capacity();
c.info().reverse().like("batBuns").like("size").print();
c.batsize();
c.batdsksize();
