As part of the ordering process of my gravel bike I was measured last Wednesday to determine the correct frame size. The measuring program didn't take the handlebar/shifter/shifter position into account in contrast to saddle make and type. I found that strange because most of the time you are riding on the hoods. It was a rainy day yesterday so I took the time to measure all my current bikes which I adjusted by 'feel' giving the purpose/riding style of that bike. Results:

So today I went back to the LBS (another 100 km round trip) to discuss this.. In the meantime the manufacturer emailed the shop a drawing of their proposal. Strangely this drawing did show the measurements of the position of the shifter on the handlebar and this came very close what I measured on my bikes especially measurement E, F and D. With the mechanic we figured out the correct frame size taking the chosen handlebar, a stem length of 110 mm and the new Ultegra shifters and the manufacturers proposal/my measurements into account. My question is what do these measurement programs exactly do? Are there people that close a bike only based on these measurements?
