My gliding days were nearly twenty years ago too, so I apologise Legalapproach. I never had access to a baragragh at my first club, so it was done by observation. If I'd taken a baragraph flying regularly
I'd have got my silver C twice over. Once at Dunstable and once in Germany.
I moved over to power after that, but hope to return to gliding when the family are grown and time is more easily attributed to hobbies.
