I would imagine there are a few slight variations on the solo theme Pobjoy.
I have just had a wee look in my old log book and I have 17 dual,3 pre solo check rides and the 3 solos - so 20 + 3 for me.
It's funny I had misremembered it as 21
When I restarted gliding in zimbabwe 1984 it took me 21 lchs to go solo - I would personally have been happy with about 5 ccts + 2 cable breaks
