That's when it tends to get really bad - even minor delays cause massive backups, because the trains are essentially running as close together as the (outdated) signaling technology allows.
Once a delay happens, there's no way to catch up other than just waiting for peak hours to pass and catching up during off-peak time.
That being said, it's still a huge step up from pretty much every other city's metro system (save for maybe DC). It's just that it's gone from being a 8/10 to a 7/10, compared to every other city's 3/10.
