...a recent classification change to the MR2 shows that indeed an incredible amount of data is needed to budge the ITAC from the assumed gains of 30%.
There's two issues there. On the one hand, it SHOULD require a really compelling stack of evidence to deviate from standard practices - hence the 75% confidence expectation. On the other, standard practice for ITB multivalve cars should *not* be 30%.

If that's the biggest glitch in how the ITAC is currently doing business, I'll take it.
