Did someone add 5* base stats for CorrinM by accident? I feel like that's what happened.
This, plus the pre-existing data, confirms the 5* base stats.
Before my edit: | 20 || 8/9 || 6 || 7 || 6
If we assume those values to be true, then these are correct:
18/19/20 || 7/8/9 || 4/5/6 || 7/8/9 || 5/6/7
