When an estimate includes the words "Late..." or "Mid...", they are about as inaccurate as possible. This is the customer and investor facing estimate. Without a doubt, they have a lot of smart people working there that know exactly what the "accurate" estimate is. But that is not suitable for public consumption, namely the investors and customers. I wouldn't place any faith in the latest estimate. I didn't place any faith in the prior one either. Or the one before that. Right now I'm treating my deposit as a 3-year interest free loan to Tesla.
