The missing detail is the medium used in your netpot.
Most folks use hydrotron fritted clay.
In which case, your drip is about right.

However, some use rockwool, I use coco.
Each has different spritzing schedules.
Rockwool saturates and stays that way for hours.
Coco can go for quite a while too, but over-dripping won't kill your starts like rock wool will.

See what I mean about pertinent information?
Better questions, better answers.
