Simple rule for centering in thermal's best lift : When the vario bips quickly, open the turn (A), when vario bips slower, tighten the turn (B). Or with other words : When "Lift increase bank Decrease" (A) and/or when "Lift decrease bank Increase" (B).
Some more explanations cause of comments : 1. Firstly, this video is not in scale (although this could be a real case...), just demonstrates the above "principle". 2. First 4 turns are in the wrong direction regarding the choice pilot makes... That has been made in purpose for demonstrating the efficiency of this simple rule !... But if you make the wrong direction turn, don't feel in dispear : just turn 270o & then go straight as long needed to encounter the thermal again ! Besides, even if you make the wrong direction turn, most of the times is better to turn in same direction & not invert. This way, you wont get disorientated regarding the postion of lift (thermal - this is a second basic general rule...). 3. Finally, the choice of which direction to make the 1st turn, depends on visual (sloap) & feeling clues. It's waste of time (as in this diagram) to turn to the opposite direction of the side of the wing that you feel more pressure at break handdle and/or lifting of your harness side...
When you are confident that you wont miss a thermal if you encounter one (since you know what to do as explained by this simple rule of thumb), you begin your flight with what it needs for it to be a great one !... ie. Confidence.
