Thank you Edwin. I saw your post last night and looked more closely at the application. Since my other son seemed to have an implied rating of around 500, I assumed that DS7 had an implied rating of 1500. But judging from the profiles for the other players (dad and babysitter) it looks like maybe it defaults to 1500. I'm thinking maybe it got reset somehow.
I asked my husband and he said he does well, but isn't all that good.
I'm going to have him play a few games over the weekend and see what happens.
