"Estimated" being the pertinent word.
Sometimes the checker underestimates the speed you can receive and other times it over estimates.
The only way you will ever find out what speed you will actually achieve is once the modem can negotiate with the DSLAM. In other words once you've chosen an ISP, paid your money and the connection has gone live.
It's for this very reason that xDSL is always sold as an "up to" product as there's no way of specifying a speed in advance.
Looking at your attenuation your sync is a little low and I'd expect it to be closer to 3 Mbps, maybe 3.5 Mbps but certainly no more than that.
As for you resetting your router "a couple of times" that will only make matters worse as the DLM will interpret this a line drops and you could find your IP Profile dropping lower.
Finally I see you're on ADSL2 (G.992.3) which given your high attenuation is pretty pointless. I'd ask to be switched to ADSL (G.992.1) instead.
