Some conclusions are obvious. If you end up landing with less than 20% of your minimum fuel reserves there were some major planning discrepencies. If your alternate has the same weather as your destination, it was probably never a good alternate. The fuel you used doing 7 approaches would have been better used heading over to somewhere with less challenging weather. If your weather forecasting infrastructure is that unreliable, maybe that should factor in your initial fuel planning, not on your 6th GA. I'm all for the causal chain of events, but the need for solid airmanship and captaincy are a constant, not a variable.
