Has the Ai become better? Or am I worse? Haha

I been warming up against the moderate ai for the past 6 months, before I go into a rank game. Sometimes to to get the edge off. Anyways, the moderate ai has never dropped 3 TCs by the 26 minute mark, until now, and has done it repeatedly. It still hits the ages at the same times it used to. I don't know about any other civs, anyone else's Ai evolving? Or am I getting worse. Asking for a friend. :)
