Not sure on the rest of the country, but this map for FL isn't different at all from what I said in this post. And if memory is correct, Florida is not different from the map prior to whatever changes supposedly happened.
Weather cycles are best described as 10 year, 25, 50 and 100 year cycles. Remember, the people wanting to sell plants to you, don't warrantee Acts of God... and that is weather.
