The simple answer is that the government teams who assess them can’t know the exact market value unless the home they’re assessing sells on the date that their assessment is meant to be for. There’s no other way to obtain the market value other than selling the actual house.
What someone lists a home for is not the market value, what someone bought the home for 6 months ago is not the market value, and about a hundred other things from renos to rezoning to even a murder can change the market value of a property overnight.
So these teams use a “good enough” approach which statistically analyze based on property size, location, age, known building information, etc. and then combine this with historical sales data to try to get a decent number so that property taxes can be applied reasonably fairly.
Yea, I think the limits are going to top out around that 300Hz mark, it’s going to be really hard to convince people they can see or feel a difference between 300Hz and 480Hz. I have no preference between 240Hz and 300Hz already.
For computer monitors, I also wouldn’t be surprised if we top out at 4k for regular consumers, with a few niche 8k products available.
