A brief note about my breathing
Peak flow is a measure of litres of air one can breathe per minute. The best I could achieve, when I was doing the Munros, was a reading of 570 litres per minute (depicted by the triangle in the above chart). This is below what it should be (about 650 - depicted by the circle in the above chart) and explains why I struggled so much during my mountain ascents.
