Firstly the official rating is always the figure that the horse is running off in the race. Therefore the figure in the daily fields should always be accurate, and the historic (ie. results) data should carry the same figures, as it relates to the information known about the runner at the time of each race.
On rare occasions there are omissions in some of the data points received for historic results which is why you are not seeing this figure in this instance. However, we correct any such omissions as soon as they occur (by populating the correct data) in the beta tables, so you will find the correct handicap rating and the correct form figures there. Thus if you run this query using the tables historic_races_beta and historic_runners_beta you will see the correct official rating and correct form figures as above for daily.
As such, it is always recommended to use the beta tables in all queries. The only reason we have not switched the naming of beta (and dropped a dual system) is for legacy users who have not yet migrated, and the fact these mirror our feeds so we can spot any issues readily.
