I'm loving this course and really getting on well with it; however ...
In Expert Skills Session 1 Lesson 7 we learnt how to do an inventory audit on 20%
I've had a go to see if I can do this on my own - my format is right but instead of getting every 5 - 5, 10, 15, 20 etc
I get 6, 11, 16, 21, 26, 31 etc. I can't work out what I've done wrong.
