Just a couple of suggestions -
1) Show people how to compute, for a given resolution, the necessary max droop rate.
For example, if max A/D in = 2.5V, resolution 16 bits, then droop should be < 2.5 / 2**17
for 1/2 lsb max droop error.
2) Also in comments suggest the importance of temp, what the source of leakage is,
and how it behaves.
