Is Sonic younger than his modern self in Adventures of Sonic the Hedgehog?

I think so. It's also stated that Tails, in this cartoon, is 4½ years old rather than the usual 8 in modern-day Sonic titles. So that means if Tails is younger in AOSTH, then clearly, so is Sonic, at about 11, maybe 12 years old.
