I personally can't imagine a platter that only weights even 5-10 pounds being slowed down enough by a short complex passage, to be bothersome. These turntables weight over 150 pounds, so, a good portion of that must be platter weight.
If a record has a passage with that much drag, what happens to the soft cantilever suspension? The stylus, cantilever, suspension, and coils with pole pieces, might be moving in and out enough to possibly cause some poor sounding results too. Possibly more bad results, than a heavy platter slowing down from this intermittently.
If you drilled a hole in the record, let it play until the stylus hits the hole, I wonder how much a heavy platter would slow down when the whole stylus, cantilever, coils (magnets if MM), plus who knows what else would get ripped out?
I don't worry about a heavy platter slowing from a short complex passage myself. A cheap light platter is a different story. That's one of the reasons why better turntables have a heavier platter. I do hear variations on budget tables, but very rarely upper-end ones. Don't forget about Newton's Law about something staying in motion.
