>Professional setup has much tighter tolerance than 3dB.
To comply with CISPR (as an example), a lab only has to validate <4.5dB (in the 30 MHz to 300 MHz range), and up to 5.2 dB (from 30 MHz to 1 GHz). See for instance [1].
By the way, if you are doing this kind of testing routinely, you need to check your PCB layout process. This fine grained tweeting should be a last resort option.
