The Cambridge capital theory controversy appeared to have been clearly settled in Cambridge, the United Kingdom's favourite, but no alternative model emerged to challenge the prevailing neoclassical orthodoxy. The paper concludes by investigating a new issue that undermines aggregate production's result, which arises from the use of constant-price value estimates in econometric estimation.

To reduce the scattered test results, a modified version of the impact test was added to the ACI 544 drop-mass impact assessment. According to the cracking and failure impact number, specimens made the most percentage increases of 63 percent and 2732%, respectively, with 3. 6% steel fibers at the top layer and no fiber at the middle layer. Comparing to the same mixtures from the ACI 544 testing procedure, the coefficient of variation value calculated from the modified impact test was reduced and increased from 20. 3 percent to 53. 3 percent for cracking impact number, from 20. 3% to 53. 2 percent for failure impact number. This suggests that the modified impact test result resulted in less scattering of results by including a line of impact using a steel bar rather than a single-point effect.
