Take Geneva 22 with a 3,4% climb gradient starting from 1500ft up to 7000ft. Standard 2,5% is 400-500fpm, (a performance check that we used to include in single engine go-arounds). 3,4% requires more like 600-700fpm. If with 10' thrust, you have to climb 5500ft you know it is going to take you already 8 minutes and there is 2 minutes left to accelerate. We have a 5' TOGA limit, but the performance tool we use is never going to warn us, it is up to the pilots to know and adapt and not think "it is covered".
At 66T GW for OAT 40°C and PA2000ft. the OEI GA gradient works out to 4•7%. So it should take even less than 8mts. That's why I said 10mts should take care off most if not all missed approach altitudes.
