Flying Med total number of hours is misleading. As Pace pointed out its the quality and relevance not quantity that is important. I would much prefer to have a captain flying my family on an Airbus who had 4000hours TT pretty much all on Airbus than a captain who had 10000TT but only 500 hours on type.
Runaway edge. A SFO certainly doesn't always give you an easy day especially if you are a new captain. Some of the biggest mistakes I've seen are from SFO's.
