1) I'm not sure whether Sneasel should be 25% for the Platinum Pokemon at Acuity Lakefront during the day. It currently adds up to 85%.
2) Staryu's missing from Canaclave City fishing with Super Rod for Diamond and Pearl (Both 5% encounters)
3) Marill should be 30% for surfing in the Great Marsh for Diamond and Pearl for all areas.
4) Barboach should be 30% for the Good Rod in the Great Marsh for Diamond and Pearl for all areas.
5) There are a number of duplicates for the Platinum fishing and surfing sections of the Great Marsh Area 6.
