There were 5,462,780 visa applications between July 2012 and June 2014. Of these, 607,880 were refused. Of those 368,000 were then checked again. Of those, 292,445 applications were issued following the review and 75,560 refusals were maintained.
So the success rate for people who apply and then appeal if rejected is 98.5%. So tough.
