[QUOTE="Pdvdh, post: 2615427, member: 4191"] As an engineer with a nauseating amount of mathematics courses, I disagree. Disagreement explained: 1) The Litz BC value is indeed, [B][SIZE=5]24.3%[/SIZE][/B] different than the Hammer value. And it's 24.3% lower than the Hammer BC value. [B]IF[/B] the Hammer value is the correct BC value, then the magnitude of the Litz error is 24.3%, and the error is lower than the correct BC value. 2) On the other hand, the Hammer BC value is [B][SIZE=5]32.1%[/SIZE][/B] (not 24.3%) different than the Litz value. It's 32.1% higher than the Litz BC value. [B]IF[/B] the Litz value is the correct value, then the magnitude of the Hammer error is 32.1%, and the error is higher than the correct BC value. The difference between the two BC values is 0.076. In example 1) 0.076 is divided by the Hammer value, which is the larger numerical BC value. The larger value in the denominator produces the smaller quotient value (24.3 percent difference). In example 2) 0.076 is divided by the Litz value, which is a smaller numerical BC value. The smaller value in the denominator produces the larger quotient value (32.1 percent difference). My percent confidence level? [B]100[/B] [/QUOTE]
