Engineering Analysis
i love the charts, but i'm a mechanical engineer... i believe they are simple enough to read for non-engineers though. only takes a little to figure out what's goin on.
i'd like to see average gains on the A minus B, but that might be overkill. i'd just like to know how it plotted.

2K to redline
3rd gear redline to 4th gear redline
Were you looking for a smoothing of the A-B plots?

I can't speak for the general public, but for people like me who came from an engineering background, I do appreciate your analysis and I think they are very concise and more importantly, to the point!
Keep up the good work

I have 0 engineering background and the line charts are a bit confusing. I think it will be for most people too. The bar charts are the most visually understandable for most people.

no, i was looking for a straight line across the A-B plots but that would make it too busy. i like line graphs better than bar graphs

Who needs a seatbelt at 160 MPH? 160 is nothing to sweat. I do it all the time.
When wheelless and motionless on a Dynapack dyno.
One thing I would add to the first graph is a label for HP and torque curves, since engineers will know which is which, others might not. Units for torque on the y axis would be a nice touch also to be thorough. Also, along the x-axis, the rpm labels a little excessive, maybe use 500rpm intervals so there aren't so many numbers along the bottom, and so they can be displayed horizontally. The labelling and key in the second graph is also somewhat redundant.
Didn't realize you used to work at Boeing. I am at Boeing in El Segundo, though not an engineer, but I work as a Contracts Manager in Finance. The charts make clear sense to me and I've been very pleased with my MD 5/16" ISO Spacer.
