I can understand how a mishandling of the controls can be put down to inexperience or lack of currency. But supposing the initial problem was indeed entering the manoeuvre too low, would that really be a currency issue?
After all the Thunderbirds pilot who crashed an F16 after getting his entry height badly wrong was not only a full time F16 pilot but a full time display pilot. In fact there was a suggestion that the regular recent practicing he had done at an airfield rather closer to sea level was a factor in the accident.
