The era in which you are building the settler and the difficulty setting does have an impact. Are you playing on Nightmare? There's a slight adjustment to training scaling taking place there but really not all that severe since the global also has gone down. I'm not sure about the underlying growth scaling factors. I'll take a look at that. Wait, I think I figured it out. I probably moved the 'extra cost' formula so that it is further adjusted by the training factors, wondering why the hell any unit would not be, but apparently the growth scaling factors were supposed to be all that controlled the settler units - and as I look closer, ONLY settler units are getting any costs from that 'extra unit cost' function (which could REALLY thus do to be renamed so it doesn't sound like a more generic application of an additional base amount for further modification afterwards!) Ok, I'll correct that. AND add a note so that it makes it clear why that function isn't supposed to be influenced by training scale factors.
