Rob Howley dejected at the final whistle after Wales' 16-21 defeat to England
But that is no disgrace – nine other nations have been brought to their knees during this record run.
Wales coach Rob Howley spent more than 10 minutes repeating the mantra of "composure, discipline and execution" that great teams follow to the final whistle as he tried to explain what he had just witnessed.
If his team had done the same at the business end of a broiling Principality Stadium occasion, England might not have ripped a result from under Welsh noses that underlined the critical few steps his players must take to turn themselves from a useful team into a great one.
It is easy to point the finger at Jon Davies's failure to find touch with a clearance kick that was instead gathered by George Ford, who launched the counter-attack that sent Elliot Daly over in the corner, but that would not explain it.
Jonathan Davies' failed to find touch with his kick which resulted in England's victory
There were a series of small moments that turned up the heat – the one time the Welsh lineout went awry and they lost possession; Dan Biggar having the speedster Daly motoring after him rather than just about any other player after an interception on his own line; Samson Lee's high tackle on Jack Nowell that allowed Owen Farrell to bring England to within two points; the chase of Davies's kick that remained too narrow and signposted the way to the tryline.
Put simply, the final minutes is when England cut out the mistakes and made their own luck. And in the face of such intensity, Wales blinked.
"If we are going to beat a team like England, we need to be focused and stay calm for the full 80 minutes and we didn't," said Rhys Webb. "It was very quiet in the changing room. We know we played well – but we let the win go.
"It is difficult to take as a loss. I don't think we deserved that result."

It is hard not to sympathise with the outstanding Wales scrum-half but, again, they did deserve it.

"We couldn't get a foothold in the last 10 minutes," said Howley, who laid down his "challenge to the players" – to keep cool heads when a Test match reaches boiling point.
Webb said every member of the squad would be "harsh" on themselves this week as they prepare for Scotland, "because that's a victory gone missing for us, we believe".
But they must also not lose sight of the fact they did play themselves into a position where they could have won, nor that from numbers six to nine they had a clear edge that only became more apparent when Webb and the magnificent No8 Ross Moriarty were replaced.

As the benches emptied, Wales became weaker while for England it was the opposite.
"It was a performance that fell five minutes short. It's tough," said Alun Wyn Jones, the Wales captain. "It was a vast improvement on the 35 minutes that have probably been missing in the past, but we fell short. Simple as.
"I said in the week about physicality, momentum and being able to be clinical. We matched them with physicality, but ultimately we hurt ourselves in those last few minutes.
"We've got two weeks to regroup. We improved on the first weekend and we can only improve again. We've four minutes to work on, probably.
