Here are four fomulas, based on the ladies LP at 2007 Worlds. (The r vales range from .76 to .79.)
1. Total PCS = .75 x (Total TES) + 13.
2. Total PCS = 39 x Ln(Total TES) - 102. (Ln is the natural logarithm.)
3. Total PCS = 23 x 1.0153^(Total TES). ( "^" means, "raise to the power".)
4. Total PCS = 2.2 x (Total TES)^.8.
Let's try Elene Gedevanishvili. Her total tech score was 44.62. The predicted values of her PSCs are
1. PCS = .75 x 44.62 + 13 = 46.47
2. PCS = 39 x Ln(44.62) - 102 = 46.13
3. PCS = 23 x 1.0153^44.62 = 45.27
4. PCS = 2.2 x 44.62^.8 = 45.92
Actual PCS: 46.81
