Do ISPs sprinkle fairy dust on your connection to make it go faster when you upgrade your service?

After talking to two techs from my provider, that's the best explanation I can come up with. They sure couldn't answer the question (other than saying they don't use throttling to manage download speed).

Even more confusing, when I signed up with this new provider, I thought I was on a 6 Mbps 300 gb/month service, but was getting up to 14 Mbps most of the time. According to the techs, only 3 Mbps was available when I signed up, so that's what my account was set up as.

Maybe the Techs were snorting fairy dust...
