Tens? Not the 100bn euro demand that was laughed out of the room? Nor the 80bn?
40 billion Euros is a big step up from "go whistle".1 And the European Research Group - i.e. the pro-Brexit Tory MPs - said in September last year that “The government should stand firm and not be blackmailed in a multibillion-pound divorce bill,” and even suggested the EU should give the UK £10bn instead for its share of the European Investment Bank.
But feel free to forget all this and just pick the largest figure you have ever heard bandied around - the gross estimate of the UK's liabilities ignoring the UK share of EU assets and the rebate - and look upon incomplete devastation as a victory.

I would be interested to see this bit. Not seen it and wouldnt be shocked if May backed down, even though I hope the leave MP's force her not to.

1The Foreign Secretary agreed with Philip Hollobone in Parliament when the latter said "Since we joined the common market on 1 January 1973 until the day we leave, we will have given the EU and its predecessors, in today’s money, in real terms, a total of £209bn. Will you make it clear to the EU that if they want a penny piece more then they can go whistle?”.
