I think the aim is to be able to derive scientifically derived, as opposed to emperical, limitations on Ops, when turbulence is predicted to reach certain levels. At present the limits in the HLL are best guestimates based on experience but do not have any basis in fact.
In a similar vein, the whole concept of pitch, roll and heave limits is being re-evaluated to come up with something based on facts and not incorrect assumptions.
