I found that it only began to worry me significantly when I started practicing at lower altitudes.
At 4 000' agl a vertical downline for a couple of secs is no big shakes but intentionally entering a one and a half turn spin at 3000' was a little daunting..then entering the same spin at 2500' I noticed how big the trees were getting!
With practice it becomes easier but it is better to start off really high and work yourself down incrementally.
The hard deck for the BAeA standard sequence is 1 000' agl so at this stage I never see any need to be anything but S&L or gentle PPL turns beneath this altitude!
