I do keep a spreadsheet with the standard measurements, plus stem length and effective top tube. But then those don't uniquely specify my particular fit to the bike, so I also have a saddle to hoods measurement. From the wide part of the saddle center, straight forward to intersect the line between the hoods. Since that's really what the reach is. Then also from the saddle top at the sitbone area to the pedal top with the pedal at the furthest extension. Which you could calculate with your other measurements along with set-back, but it's easier to just measure.
