I'm in two minds with this issue. We had a lot of tuning problems on the Super Taipan at Forster and consequently our results were mixed, however it does appear that it's pretty easy to have a good result on a Mossie F16. Generally in mixed fleet racing you will see a bit more diversity in the winners accross differing conditions ie one wind strength will work to some boats performance envelope better than others.
I think I only had one race all weekend that I was happy with as far as the boat performance and our tactical decissions, that was the last race on the Sunday. We won over the line by miles but if I recall correctly it was close on hcp to the Mossie. The conditions were perfect for the super taipan in that race, we were fully powered up for the upwind legs and were the only boat to be fully powered downwind, the net result being that we beat the Tornado by a good margin and the rest of the fleet were way back.
I am in no way saying that the mossie sailors are not good but it appears that the hcp is leaning towards generous.
