I wouldn't feel confident about it. Taking a closer look at things, since we have no daily ranks for PMP! it is possible. First week sales would need to be about 80% frontloaded into the first day, but on occasion that does happen, like the last Berryz single. I might try some searching to see if there's more data we don't have around here.
