Attentional's Performance Index shows how programmes have performed against the genre average for their channel and timeslot. The benchmarks used have been developed and tested by our statistical experts to provide a robust performance measure. It therefore offers a like-for-like comparison, reflecting the fact that genres as different as Drama and Current Affairs cannot be realistically expected to achieve the same audiences.

Score

Summary of Performance Index scoring:

A programme is deemed to be performing in line with the benchmark when it has a score of 100. A score below 100 indicates under performance, whereas a score above 100 indicates over performance. Within those scales of performance, a colour coding has been applied to give a clear quick indication of programme performance.

Score	Rating	Score	Rating
0 - 50	Very poor	91 - 110	Average
51 - 70	Poor	111 - 150	Above average
71 - 90	Below average	151 +	Excellent

 

Technical Information:

The Performance Index is calculated using 365 days worth of programme data, to ensure that a representative sample is used. The 365 day period is calculated as the 365 days immediately preceding either the transmission date of the programme being benchmarked, or the latest available programme data date (whichever is earlier). This 365 day period is shortened if the channel in question has not been supplying transmission data for a sufficient amount of time. An index is not produced if the channel has been supplying programme data for less than 14 days, or if programme data is missing from more than 10% of the benchmark days (due to unavailability of BARB data on certain days). Initially an attempt is made to calculate a benchmark figure using programmes only from weekends or weekdays (depending on the day of the programme being benchmarked). However if less than 3 such programmes are available the day-scope is expanded to include figures from all days of the week. If after extending the benchmark criteria to all days of the week there are still less than 3 programmes available from which to produce a benchmark the Performance Index is deemed to be invalid. A figure of 100 indicates that the programme share was equal to the benchmark share. Figures above 100 indicate better performance than the benchmark, while figures below 100 indicate worse performance.
