Where every number comes from

Published rows come from a named public source. Calculated rows are worked out from published numbers with standard physics. Estimate rows are engineering judgement, or rest on one; on screen they carry an est. mark. Every engine runs through the same physics, so differences come from their inputs, not from different maths.
