I can't figure out why humps down the straight was to anyone's advantage. A real signature trait among American Tracks. The Monarch is my favorite.
Mark,
I don't think the humps were put there for anyone's advantage - perhaps more of a disadvantage.
To me good racetrack design is very similar to good golf course design. If it were simple, it would not be a challenge and a lot of folks would not enjoy their time and come back, just to try to conquer the features that the designer put in to keep them from running flat out. The "Esses" and the humps or fall away straightaway are all little things that must be overcome. Elevation changes to do make a track interesting to drive, be it in 1/24 or 12 inches to the foot. I remember going up to Watkins Glen to watch the Can-Am cars - mostly to watch Mark Donohue's Lola - negotiate the fall away straight leading into the hard right turn. It was exciting.
Recently I've started to race at a facility in Holly Hill, FL - The Race Place. The track is rather unique and it has a road course that can be added or deleted from the track by means of some 'switching blocks'. The photo below shows most of the track:

Talk about a feature-filled short section of track! This seems to have it all. There are so many "blip and brake" sections in this road course that it really takes some time to learn. As you enter the "infield" you are greeted with a sharp left hander that leads into a punchable banked turn. That sure does provide you with a false sense of security! You can not slow down quick enough for the quick left hander that leads into the fall away straight away. If you take it easy through the banked turn, then you can set up for the fall away and then the sweeping "Esses". There are all sorts of places to make up time and also lose control of the car at the same time. The fall away straight that leads into the hard right hander is very reminiscent of what I saw in Watkins Glen many years ago. It is a track that offers you a challenge and is simply fun to drive.
Someday I'm going to get to Mike Swiss's place. I've read about his flat track and it looks like a driver's track!
Of all those listed by Cheater, just give me the 90 foot "Black" track - the one that is flat - except for the humps. My favorite track of all time.
