The problem with having such an insanely high gear is that the robot will be very hard to control. Another issue with such a huge difference in gearing is momentum. This year, my team used AM supershifters at 5/12fps. If we we were in high gear then switched to low at full speed, we would tip over 75-80% of the time. Imagine how bad it would be going between 17 and 5.

I'm pretty sure 111 did a 3-speed this year. Also, how could 4 speeds possibly be beneficial, even as an autoshift?
