Evie, Unfortunately statistics rely very much on who pulled them together. So for example the stasitics you quote about WAS not returning if there is an A after they have left the M may have been compiled by someone who has done just that. They may only have done thier research amongst people who fall into this category. There will be a different set of statistics somewhere that has been drawn up by someone in a reconciled M. They will paint a different story.
As Naej said the important thing is that you focus on you. You may or may not be able to bring your H home but statistics certainly won't they are just numbers from a past event.
