To be quite honest, if it's a designated competition and the published start time is 10am then you really have no grounds for complaint.
Let's be fair, here. Say, for sake of example, you started an hour early for "domestic reasons" and played for an hour in benign conditions, and then the wind got up around 10am and the rain came down, you would have gained an advantage over the rest of the field by starting early. Do you think that's fair? I don't, to be honest.
You may feel hard done by, but I suspect your club has been running competitions for many, many years. If their arrangements don't suit your circumstances then maybe you should seek out a club where you can be accommodated rather than moaning about the perceived unfairness of it all.
