@DavePerry2012 This was the first record, on 1 Jan 2003. She lost the record to an American later that year, before it was published in the 2004 edition, so they did it again on 1 Jan 2004. Kago shared that second record, and it's the one that made it into the 2005 and 2006 edition.
She has said on her blog that being pregnant with and giving birth to her daughter took away much of the strength and endurance for which she was famous. The EC graduation concert was more difficult for her than any concert before her hiatus. Basically, she's lost a ton of weight, almost all of it muscle.
