I thought you could restart from the point you had to break with no loss of points in the case of a "break break break" coming over the radio.
Even if you can't, it's better to loose some points than have a mid air !!!
Quite a few people practice north of my house; south of Breighton on the Hull-Selby railway line... the amount of times I see one aircraft doing aero's and another bimble along the track of the railway line on the way to (or back from) look at the Humber Bridge is frightning.
It's difficult to spot other aircraft at the best of times IMO, so when you doing aero's it add's to the work load.
Not sure what the answer is, albeit I try get a FIS, but the problem with that is you can get so much RT traffic you can't focus on the Aero's.
