While I do believe the advantages and would want more weight off the rotational weight vs static weight, even Brads article kind of confirms, that at the rate of witch a car accelerates in the 1/4. that it isn't even Close to the 1# to 3# difference advantage that is and was Advertised of the Physics back in the day or even today. To be accurate, It would have to be Time specific of time traveled with rotational weight differences vs static. Actually more to it then that.

As far as the article, it even shows a lessor gain from the rule of thumb .1 ET for each 100# loss from #3 test, but more, then on test #4

Test 3 shows With a 53.74# weight loss of Rotational, a .034 Gain.

Test 4 shows With a 82.08# weight loss of rotational, a .110 Gain.

Even this testing has accuracy issues. But, All can and Should conclude. No where close to the 1# to 3# advantage of rotational vs static. That I hoped for and most others, not down the 1/4 anyways.
