Originally the radiation efficiency was listed as 92%, this was a mistake.
These values are based on simulation, actual measurements are below (they are very similar).
The center frequency may shift a bit between batches as a result of variations in the dielectric constant of FR4.
Also, not all brands of FR4 have the same dielectric constant. Frequency shifts up to 100 MHz are normal.
