Sorry, Craig. I'm not a fruit crop expert. My discipline is in ornamentals.
Someone from the California state extension service could probably help or another avo grower (you have coops there, right?) or maybe you could find the info online through a Google search.
As an aside, I bought some that looked like those a week ago and they were just fine, aside from being a little on the small side....
PS: you win...you stumped the Baz!
