Why have I received more/less packs than I have sent?
The algorithm for selecting addresses is complex. There are instances when your address will be selected more or less often than you expect. Since it can also take some time for packs to arrive please have patient, your sent/received numbers will even out soon.
What is a personal rating?
A personal rating is a reflection of your feeling about the pack you received. The rating is used to be better able to match senders and receivers. The sender cannot see your rating of their pack.
