:The Kanahele (1997) source is from a larger EIS.  I'm not at home and I tried to open it up in iBooks on my iPhone and it was so large it crashed. I'll keep working on it, but I don't see an immediate problem with the dates. Kanahele is relying on older data, so we need to see where it is coming from, since this wasn't published in a journal.  No problem just yet, but remain skeptical as you go.  I'll have more to add later when I have access to an actual computer.
