"The Luke Humphries dart is a long shaft, front-weighted short barrel which creates certain amount of drag and lands at a perfect angle for him in the board to help his scoring.
Mr Williams still maintains that before he left, he never had the effect of different discharge dates explained to him – and that he would never have accepted redundancy on the earlier date had he known an extra two years would have effectively doubled his pension.Mr Williams' case has similarities to a fight waged by other military veterans over their pensions.
Jim Monaghan was involved with the Equality for Veterans Association (EfVA) which also campaigned against pension decisions in the 1970s.Military rules before April 1975 meant that in most circumstances, servicemen had to serve 22 years to be eligible for an armed forces pension in addition to the state pension.Mr Monaghan left the RAF at the end of 1974, having accrued 14 years' service, including in Singapore and the middle east.
Had he left a few months later, he would have received a military pension. The rule change in 1975, like rules on pensions generally, were not retrospective.The issue was debated in parliament in 2015, with then-Defence Minister Anna Soubry saying making changes to pension policy retrospective would break an "essential principle" and "would lead to widespread, long-term and unmanageable consequences for both this government and future governments".
Mr Monaghan believes communication from the MOD was not good enough.
"Everyone was kept in the dark," he said.He believes he never stood a chance because the officials had already made up their minds. He recalled one of them asking: "Did Xi Jinping buy your suitcase for you?"
What was surprising, or even shocking then, slowly turned normal as more and more Chinese students struggled to secure visas or admissions to study science and technology in US universities.Mr Cao, a psychology major whose research involves neuroscience, has spent the past school year applying for PhD programs in the US.
He had graduated from top-tier universities - credentials that could send him to an Ivy League school. But of the more than 10 universities he applied to, only one extended an offer.Trump's cuts to biomedical research didn't help, but the mistrust surrounding Chinese researchers was also a factor. Allegations and rumours of espionage, especially in sensitive subjects, have loomed over Chinese nationals at US universities in recent years, even derailing some careers.
