I wrote the "Gravitational and Kinetic Energy Equations" article as a replacement. If there is more, accurate information that you'd like me to add, let me know. Perhaps a portion on converting chemical potential energy to work? Any such attempt needs to reference the BSFC wiki.

The reason i haven't just taken down the existing wiki page i wrote is because it was written to show users that are not very mathematically inclined what effect weight will have on their fuel efficiency. The articles you wrote are great, however dont give a path from accounting of the loss of energy to fuel use, most users (i think) are not going to care what the energy is that they are wasting rather they will care what fuel relates to that waste. in the original wiki page there are large assumptions of the efficiency of converting chemical to mechanical energy and i would be very happy for a more accurate method of calculating this conversion. I got these assumptions directly from the ecomodder online steady state efficiency calculator. I am also open to democracy, if everyone thinks im crazy and my original wiki page is inaccurate and not worth keeping up and the new clearer articles are a good replacement then im happy to take the original one down. I have gotten what i want out of the calculations, its up there for other people.
