I gave an adrenaline rating for a (stated) family ride.
This is great but could be all the better. The idea itself is ingenious; I love that you took the basic Schwarzkopf fairground looper layout, scaled it down, and removed the loops. Really smart and well done.
My nitpicking criticisms: 1) It really loses its pace towards the end, partially because of the MCBR which is really unnecessary in a track of this length. I would have rather seen brakes before the last 180degree turn, and then the MCBR could feasibly be removed. I see what you were going for in terms of idiomatic MCBRs, but the track length was just really short for it.
2) Some of the shaping or banking was a little wonky, just for example I wasn't sold on the banking you chose for the top of the first hill after the main drop. I feel like a true Schwarzkopf would be banking into the next turn by the top of that hill, but maybe not.
That's about it. A simple but solid track that does what you promised.
