Diotima is an intrinsically more risky project target object because if the asteroid presents its low-amplitude (0.06 mag.) aspect during this apparition, it'll probably be too small for us to measure even with a successful observing plan. Writing up a negative result takes a bit more effort because you need to be very careful with error analysis at every step, so that you can precisely specify at what level you didn't detect the signal.
