I have been building a master list of my HPR rockets using data from Thrustcurve, so I have a shop-reference Pivot Table. A (previous?) bug resulted in the Excel output being in SI units regardless of preference of the HTML output, so I've gotten in the habit of automatically adding a column here and there and doing a quick mathematical conversion to get to my preferred thought-units (ft). Low and behold I picked up the project tonight after putting it down only yesterday, and am stunned that my 38mm Norad Pro Max is expected to hit 2000+mph and exceed 15000 feet on a CTI 38mm motor...after checking myself, I realized that I was applying my SI-to-imperial conversions to numbers already in the imperial unit...COOL! But now it doesn't match the previous several hundred lines of entry in my master list! Going to convert my preferences to SI, and run the extract again to see if it's resolved...
