The assessment is off by 10% or so and it won’t impact your taxes… appealing seems like a huge effort for very little to gain. If your valuation is high then everyone of your neighbors will be too, they use the same methodology for everyone.

Increase is likely systematic, but if you're looking for idiosyncrasies I'd: compare the cities metrics YoY, n vs the independent appraisal. Then flup w the city for clarification why something seems off.
