I have TWC's old 200/20 plan from before they got bought by Charter and speedtests come in at somewhere lower than 200 during peak periods, so it definitely still happens. However, it's not noticeable in regular use (with the exception of YouTube, where it occasionally stutters at peak times). YMMV, especially if you have a lower speed tier.
