Please don't feel like I am trying to go against you, I am very impressed with your posts and anyone that knows me will know I am a big believer of knowledge sharing and helping people, hence I try to make my post as factual as possible.
So for information sharing, I have just measured and tested several different radiator valves we have here (when we first started selling evohome we produced our own compatibility chart as there wasn't any guidance on TRV's and what would fit HR92's) and the pin stroke on them is typically 2mm from open to closed - the thing that does vary is the pin height by about 1mm (so some 14mm and some 13mm). If the HR92 calibrated a 13mm pin down to 11mm and back up, it actually wouldn't need to go all the way to the upper stop to have the valve in the fully open position.
As for 'Full-stroke mode' we have customers who always ask what battery life is like on these and two years battery life is a much better selling point than a year! If I was recommending changing setting 6 then I would fully explain the negatives of doing so and battery life reduction by typically 50% is a major negative in my opinion.
