+We evaluated a total `r format(n_forecasts, big.mark = ",")` forecast predictions from `r n_models` forecasting models, contributed by `r nrow(n_teams)` separate modelling teams to the European COVID-19 Forecast Hub (Table \@ref(tab:table-scores)). `r sum(n_teams$n>1)` teams contributed more than one model. Participating models varied over time as forecasting teams joined or left the Hub and contributed predictions for varying combinations of forecast targets. Between `r round(per_week[["Min."]])` and `r round(per_week[["Max."]])` models contributed in any one week, forecasting for any combination of `r 2*4*32` possible weekly forecast targets (32 countries, 4 horizons, and 2 target outcomes). On average each model contributed `r format(round(model_forecasts[["Mean"]]), big.mark = ",")` forecasts, with the median model contributing `r model_forecasts[["Median"]]` forecasts.
