Leena's pattern system is a proportional system and if you are not proportional (most people are not!) you have maybe to change some measures. This is the case with all proportional systems.
In the old forum PMUG Susan asked about a forward posture alteration.
If you look under "Help" in PM you will find a topic named Manuals. Here you will find a .pdf written from Thea about (Leenas) Balance faults (or something lik this) and there is an excel table. With the help of the table you can calculate your balance. If you do what the table suggest you will get a fitting pattern.
