It's not a math problem so much as a data problem. Aerodynamic coefficients are simply difficult to nail down with the precision that a lot of ELR shooters want. We know how to calculate drift. Hell - decades ago, they figured out how to calculate the drift when a howitzer projectile is shot 80 degrees into the air, fails to nose over, and falls backwards, reversing the drift on the way down.

It's the uncertainty in that calculation that's being pushed. We can calculate the moments of inertia to near perfection, but the overturning and lift coefficients are still kind of spotty, especially for new ELR bullets. Measuring or calculating those with more certainty is what is needed, not a new way to do the math. The BRL and others figured this out long ago. They just didn't care about this level of detail.
