I think you have missed the point. The point was just because they are forecasting on the automated forecasts an 8 it doesn't mean that is what is expected as they automatically rounded it up.

The 8's on the forecast maps or in reality the 7's that have been at times widespread over past weeks will be due to lower then normal ozone above.

Friday forecast:

8s for the most of S England & S Wales ; 7s up into the Highlands, even N of Aberdeen.

6 for the N of Shetland. As good as it gets (apart from the rare 9s in S Devon Retron sometimes spots!)
