Janice Okubo has said that for Oahu births the BC# was assigned on the “date filed”.
Ok. Thats what I assumed as well. And if the Nordyke and Obama COLB's were 'filed' on the same day (the dates on the forms are 'Accepted' not 'Filed'), it is still very plausible that the forms were filed such that the Nordykes would have lower numbers than Obama.
