You made me think and so I did a search. Some say it's the difference in variety, but I found this and if you scroll down to Food Tips on the lower right side, there is a similar statement:

So I don't know, it's just something I've always done. Four bumps get frozen and used for cooking later and 3 bumps are eaten fresh. I'm not sure where on earth I gathered that little bit of info.
Have fun!! And let me know what you think.
