You need to "soft pedal" when shifting. In other words, the problem you're experiencing is most likely caused by "lots of torque on the crankshaft" as you say. When shifting, ease up on the torque, even though you keep the pedals moving............and as I believe Ned Overend once said: the front derailleur is the weak link on a bicycle, use it as seldom as possible.......Or something like that........I'll add that, since you've already utilized the excellent instructions on the Park Tool site, if you've got a barrel adjuster for the front derailleur you might try turning it clockwise just a bit to loosen the cable tension a little. That will make downshifting with the front derailleur a little more responsive. But mostly, "soft pedal" when shifting-
