IACC Rule DSP limits

[jboat]

The formula for the rated Length (L) and Sail area (S)

L = LM*(1+2000*(LM-22.1)^4)
S = SM*(1+0.0001*(SM-320)^4))

LM L
22.15 22.426875
22.14 22.2533568
22.13 22.1658506
22.12 22.1270784
22.11 22.1104422
22.1 22.1
22.09 22.0904418
22.08 22.0870656
22.07 22.1057534
22.06 22.1729472
22.05 22.325625
22.04 22.6112768

limiting possible values of LM, whether larger or smaller than 22.1, and similarly for possible values of SM, again whether larger or smaller than 320. This has the effect of limiting DSP to not less than approx. 23750?

L + 1.25 X S^2 - 9.8DSP^3 <= 24*0.686

Is this what the rule intended, or just incidental due the mathematics of ^4?
