Was Post Office Investigator Training on Horizon Enough?

Was Post Office Investigator Training on Horizon enough? We've heard about some investigators getting a day or two of training on the usage of the Horizon system in a Post Office but were they trained on how to analyse the audit data coming from the Fujitsu Horizon system that was so pivotal in many of the private prosecutions of subpostmasters brought by the Post Office?

We analyse the training described by Raymond Grant, former Post Office Investigator in his evidence to the Post Office Inquiry and ask - Was Post Office Investigator Training on Horizon Enough for them to competently complete the investigations they were tasked to?
