Yes, there was actually no problem from the Examiner when I checked my calcs via email/software/app (see my response to Genghis, the "toilet" bit was meant as a joke, I'm afraid that didn't come across). I was however "caught short", since I didn't anticipate being asked to plan a navex (that much was true in my apocryphal tale). Hence I didn't have any of my usual kit (iPad/AirNavPro/SkyDemon) with me on the day...hence the email app was very valuable. That's it.
ps I've got two Landrover Defenders. Given your name, I guess you have some ?
