aa,
Most important thing is to relax, and if you can do quite a few from a higher height, then you will have the chance to "see" how far the aircraft goes under different configurations. Don't try to push yourself to reach a particular spot, rather start at the same spot and develop a feel of where it goes to, then later you will naturally 'look' at the spot and be OK with it.
Think also about the different phases of flight, even for normal flying, Climbing, high power low airspeed and approach, low power low airspeed, don't just do all auto practice from the cruise.Learn to get the A/C configured quickly into the auto configuration.
One tip is once you have joined needles remember that from then on the engine is transmitting some power to the rotor system. However slight it WILL alter your auto profile and mess with your judgement later. Once needles are joined, then look away from your spot, concentrate on smooth power application and a good climb away.
In fact experiment with that to see how much further you will travel and then you may reason, which judgement would I prefer? The one that shows the spot to get to with engine failure or the one with extra power helping me crash into the trees further?
all good fun
