For example, take Columbia Heights to Foggy Bottom. 2 transfers (yellow/green -> red -> blue/orange/silver). Red line is red line, expect 10 minutes on the weekends if you're lucky. The B/O/S at metro center are frequent enough (except when they're not; I've seen 20minute headways enough times that I'm leery of even trying), but the Green/Yellow lines I see an average wait time of 10-12 minutes on the weekends. That's about 20-30 minutes of waiting.
