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 3. 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.
