I just ordered Infinity #2 but the speed estimater said I'd get around 25mb/4mb. I asked the customer support if I could easily downgrade to Infinity #1 if that estimate was correct and they said yes so I decided to roll the dice and go for the top package just to be sure. I've read a few posts saying the estimate is always lower and I'm hoping that's correct? I remember the estimater saying I'd only get 6mb from ADSL but I had 16mb on Bethere.
The estimates are normally accurate, you do get estimates thare sometimes way off but are rare. FTTC is measured in distance to the cabinet and not distance to the exchange like ADSL.
I was estimated 65/18 at my old house but only got 45/18, and was estimated 11.8/1 at my new address but get 58/18. It really is luck of the draw! 😛
If I could get 39+ I'd be happy as that's higher than Infinity #1 so I wouldn't feel bad about taking a gamble. I just hope the install goes smoothly after reading all the horror stories about engineers not showing up.
I would have ordered the lower package as its easier to step up than down. If you line syncs at full speed then you know there's a good chance that it will go higher. I think you'll struggle to step down as your contracted for that amount!
Hopefully all goes well for you then! 😉
