I think most people get a feel for whats happening in there tank - They know if how there fish behave - Where they hide - How and where they like to swim and subtle changes are easily spotted by most
I rarely Check it - Like most - twice a week to begin with then the day after a water change
Then when I dig to the back of my fish cupboard and find the kit about 1-2 months.
I did do a few checks after I changed my substrate to sand though - nothings changed
