Max, the variances with your speed of around 2-3Mb are negligible. You should know by now how SRA works. Its not going to make the slightest difference to how you use your connection.
I can't believe that yet again. you are pestering Clive Selley's office. You should know by now that it's not going to make things happen any sooner, nor will they be able to give you any more info. Can you imagine if everyone did this - they do not make any special exceptions for Maxdsl.
>> I will think very hard to decided with three options:
Its not yet May, but we've been over this before and no matter what we recommend, you still seem to ignore what we say... then you regret it.
You don't need 330/50, nor can you afford it. Also, because you can't get the full 330 it feeds your addiction to check stats which just stresses you out. No matter what you say, you just cannot resist checking your speeds and then you get worked up if the speed decreases. It should be discounted because it really is not suitable for you.
You may as well forget about 40/10 too. You wont be happy on that and will be moaning and itching to switch in a short timespan. You will never, ever be content with 40/10 when you know other options are out there.
