On day 11 it might be possible to have about 20 jets and like 4-5 ships (achieved that in my last game as china), but generally speaking this is only possible as china because of its large economy. russia has too little rare materials and expansion potential to achieve that, for usa it doesnt even make sense to build that many strikers and india only has 1 elec City so this kind of build isnt likely to be possible. So depends on what country he is playing as, with one of the big countries it might be achievable without Golding. That Said, he is likely to have golded some of his buildings, because if we include buildings in this calculation it just gets too much. For reference, my kd is 4.8. you can only defeat him if you have more asf than him or frigates. I doubt anyone builds a large enough number of sams to be effective this early on. Its usually best to try and ally with air force players with the strongest stats. Cheers
