Well, that could be the issue - I will on average only drive it on 3 days of the week (I only commute to the office 2 days a week) so it's regularly going to sit on the drive for 2 or 3 days without moving . And on basis that alone, I'm tempted to think that keeping it at 80% and throwing it up to 100% occasionally is probably a better way forward.
