performance of (93.9, 48.0)%-ile. Clearly, as found for re(N-O), top performers for Δre(H-C) do not typically repeat a strong performance for Δre(C-N). with a Δω(C-N str.) performance close to 90%-ile is revM06-L, but in this case the associated Δω(H-C str.) is only 8.8%-ile. A summary observation regarding the Δω(C-N str.) data in Figure and Table is that the DFT ladder achieves limited success after the Group 4 debacle, but the overall performance along the way is fraught with inconsistency. 3.8. Performance Consistency. An analysis of consistency was conducted by first singling out the DFAs that were the best performers for each fulminic acid property discussed here.
