Did you sit the APM June/July 2020 exam?

In the examiner’s report for this exam it mentions the below about Question 1(iii):

‘In this question, technical knowledge around a particular technique was being sought initially, followed by an evaluation as to whether key performance indicators measured the particular technique.

It was obvious in this part of the question that candidates could not undertake the necessary evaluation and it is very important for successful performance in future diets that this key skill is demonstrated.’

Can anyone remember and please tell me what the technique was? Thanks.
