ChNN treng mo/mala-divination question

[climb-up]

In ChNN’s book on mala divination he says that for more important questions we should generate the three numbers three times and then ‘find the average.’

How exactly does that work?
You can’t add and divide by three, so do you:
-add each sets of numbers and then subtract three from each?
(Eg. If the fist position was 3,2,2 we get 7, subtract three twice and end up with one)
Or
-do we interpret each of the three and find a theme, or larger answer, within those interpretations.
