In answer to 2 - read the selection criteria. Firstly, results are no longer the sole factor in selection, and secondly it was openly stated that existing team members, if not up to standard, would have a 6 month grace period in which to come up to scratch before potential de-selection if there was no improvement. Not quite "sorted" as you suggest. Finally, as the parent of a GB Development Squad member, please don't take your own vicarious disappointment in your child's non-selection out on those who were selected by denigrating their achievement. If you and your child feel wronged by this selection, work hard with them, train harder still, don't carp and prove the selection panel wrong!
