Patrik : I did not understand very good why you say "9.Nh5 sucks" but about my drawing chance, I agree that when you play a gambit, it's not to fight for a draw. But the variation with Nh5 need more practice to see which move offer White the type of game they want. And now Iam practically convinced that 10.Nxg6 followed by 11.Bd3 could be the main move in the future. Not that 10.Be3 is bad, but it's harder to play for White than Black here. I have not made any real error, but surely somes microscopics errors and now it's hard to assess if my compensation is sufficient, and I don't like my position that much now(I never liked the too closed position reached somes moves ago), and it's because I am objective that I say that I am playing for a draw now. And for a supposed unsound or even a refuted gambit, with not the best moves played, a draw is not a so bad result
And when you say that 8.Qf3 is refuted just because 10..Nh5 seems good is exagerated. Even if my move 10.Be3 is not very promising against Markovich's defense, it might be playable with somes improvements. 10.Nxg6 and 11.Bd3 is definitively the best move in the BDG spirit, that I will use for sure when I will face 10..Nh5 again. If 10.Be3 and 10.Nxg6/11.Bd3 is losing, then you can say that 8.Qf3 is refuted due to 10..Nh5! but the future with more practice will tell us what is the truth. If your "ED theory" is true (Personnaly, I don't really believe that White should always have +/- even if Black play the best moves) and if the BDG=ED theory (why should it be better than another normal opening?), then, a draw is a bad result for White in the BDG. But let's come in the reality, things are not that easy. With the best defense, Black have equality in every major defense against the BDG, and most of players believe that BDG is bad, so, I won't feel sad with a 1/2 result with a pawn down, but I agree that in this game I never reached the type of position that the BDG player wanted for, but I wasn't playing for a draw either. Wathewer will be the result, I still think that 10.Be3 is playable, but no more. Let's look at 10.Nxg6/11.Bd3 in the future.
PS: sorry if my English is a little weird to read, but can't explain my ideas as good as in French because I am still learning that language at school.
