[QUOTE="tareload, post: 189745"] Yes, that's exactly my point about Tru-T and why I spent so much time daylighting the fact it's usually way high compared to Vermeulen. Here's your numbers with Vermeulen: [ATTACH type="full" alt="1603842826786.png"]11314[/ATTACH] So about 50% high (typically 20-50%) with Vermeulen; point taken with Tru-T. This was the whole gist of my work over in the other post. As [USER=38109]@Cataceous[/USER] and I agree, using one of the dated empirical calculators or Vermeulen will typically get you much closer to your measured value.
