Jack, I had an idea. I don't know if it has any merit whatsoever, so I thought I'd quickly run it by you. Until such time as my logging becomes first class, what would you say to logging every row in realtime, then going through the log (without the chart) as part of the debrief, and distilling it into an abbreviated version which only contains the necessary rows, and in doing so, rehydraulize the day purely via the log. Just a thought, and if it has no merit I will happily dismiss it.
I was going to xfer the main post on Beginner Internals from word but it is too long, I blieve. In the post I mention an attachment: the zone chart. see below:
