LTC3110 V MID capacitance

The LTC3110 datasheet states the following:

"If using a single V SYS capacitor where balancing is not required, a capacitor of at least 100nF must be connected between V MID and PGND."

 

However, elsewhere it states:

"If the output is not used, a compensation capacitor of 1nF must be connected between pins V MID and PGND."

and 

"Generally capacitors with equal value of at least 1nF should be connected from V CAP to V MID and from V MID to PGND if the output is unused"

 

Is 100nf required, or only 1nF? Also, is the capacitance just needed between V MID and PGND, or also between V CAP and V MID?
