First thing - look at the figures and reassure yourself that you've practiced them all recently! Nothing as scarey as seeing something you've never flown as that will screw up your calculations.
Then make sure you are happy flying the figures next to each other.....
Then start at the final figure, work out what height you want to exit it and plot backwards working out start and finish heights for each figure until you work out your start height for the final wing rock (which should be S&L) just before you start Fig1.
Then work out where you want to be laterally in the box to best show the a/c and to best disguise and fudging you may need to do....
Then go and learn the sequence by heart
Then go and walk it through - reciting gate data (speeds in and out,heights in and out).
Then go and try and screw up the competition by gamesmanship!
Good luck!
