I spent my first 9 years living in Boston suburbs. Now, you have to understand that back in the 1950's, Americans didn't move around as much as today. There were distinct regional accents all around the country. There still are some, but they are not as strong as they used to be. TV has, over the decades, pretty much eliminated that.
So, as a child, I had a typical strong New England (and specifically Boston), accent. When I was 9, my family suddenly moved to Petersburg Virginia! Oh horrors, a Yankee thrust into Rebel territory! ;) I was the only student in my grade school from north of the Mason-Dixon Line... One classmate was fresh from Georgia; I couldn't understand a WORD she said (and I'm sure she couldn't understand me either).
Neighbor adults were scandalized by my "rudeness". Where my word for "yes" (in response to an adult's question) was "yeah", the local kids said "yessir" or "yes'm". A female relative was "ant", not "aughnt". One difference that I can't shake even now: Highways are "routs", not "roots". I will say that living in Petersburg produced a life-long interest in The Civil War (or as the local adults called it "The War Between The States" or even "The Northern Aggression").
When I was 13, we moved to Maryland and trust me, Baltimore accents were not much easier to understand. So I made a conscious effort to change my accent. National TV evening news helped a lot, but all TV shows used a "standard" inflection (later called "Johnny Carson Midland". Heck, even Captain Kirk and Mr. Spock spoke that way. :)
So, my adult accent is indeed exactly what shows on the chart; "Midland with some New England influence". Still, if I could time travel and talk to my 8 year old self, I would understand him perfectly. If I travel to New England for a few days, the old accent returns...
