As much as possible. Depending on your level, you may want many more of them (most events have level scaling - enemies in nodes, including boss nodes, will be powered up at about HQ level 40 and 80).

In short, regarding events' difficulties, there are 3 of them:

Easy: HQ level 1-39.

Medium: HQ level 40-79.

Hard: HQ level 80 and above.

Therefore. it's best not to run sorties on maps with give you large amounts of admiral EXP such as the "Extra Operations" maps and 5-4 when an event's starting day is approaching.

That's all I know. I wish you the best of luck in stockpiling your resources as well as clearing the event.
