Flatness of a table saw table: How perfect should it be?

I was using a digital level on my table saw's table today and, in addition to a 0.00 reading in a place or two, I was getting readings of around 0.34, 0.80, things like that; virtually all less than one degree.

Should I expect 0.00 everywhere? Is that what most people get or is that unrealistic? How much variation is acceptable?

Thanks in advance!

That doesn't sound too bad but I'm not really familiar with that approach to checking flatness of a saw top.
I like to use a short precision straight edge and feeler gauges.
The real proof is squaring the blade checking both side and splitting the difference. A reliable square is a good idea .
Then make a couple cuts and check the results.
Good Luck

I haven't heard of anyone using a level on a tablesaw to determine flatness. I suppose conceptually it could work, but flat is what you want (i.e. all readings the same, whether they're zero or not), not particularly worried about level (zero). I'd go to the straightedge method, frankly.

Put the toys away and start cutting. If its clean then who cares? Do not go looking for problems unless you can connect it to a known cut issue. If it cuts clean and square leave well enough alone.

It has never occurred to me to test for flatness. My saw looks flat and cuts clean so why bother?
