Lyons against the county as a whole: no difference the data can distinguish from chance, despite a 1.0 point gap.

Does hiring someone help?

Whether an agent helps is not settled here: the advantage has changed sides between years, ahead in 2 and behind in 4. A single combined figure would report whichever side the window happened to favour.

Each year: how many percentage points better an agent did than an owner filing alone. Negative means the owner did better.

Firms that file on your behalf commonly take a third of the first year's saving. This is the county's own record of how the two groups actually did.

The reasons the Assessor gave

Every decision carries a stated reason. These are the ones that appear most often on Lyons decisions, and how often each was attached to a reduction rather than a refusal.

Reason given	Decisions	Reduced
This is a result of a market analysis of your property as well as an analysis of comparable properties.	6,166	17.3%
This is due to an analysis of the actual sale transaction of the property.	215	0.0%
This is due to income, market or cost analysis supporting the assessment.	119	0.0%
This is due to your property's uniformity with comparable properties.	49	0.0%
This is due to insufficient data having been submitted for our review.	27	too few

A reason seen fewer than 30 times shows no rate, for the same reason a township with a handful of appeals shows none.
