I've been doing Amazon PPC for a couple of years now.
The author of this course is clearly very intelligent, he uses some very clever spreadsheet tactics to keep on top of his bidding strategy. I gained some very important insights from this course. However, the course is not very well organised, and misses some key concepts. He doesn't for example, go into much detail about lookback windows, which is a crucual concept.
Another course I'm currently going through, Stephen Noch and Andrew Bailiff – That Amazon Ads Masterclass (which you'll find on this forum), is much better organised. They explain in detail about how to use dynamic lookback windows based on the data in the lookback window best matching the upcoming period that you want to optimise for.
The Incrementum Digital course also doesn't for example, mention using lifetime data to consider pausing low volume keywords that haven't converted after a certain number of clicks (The Stephen Noch course hasn't mentioned it thus far, but I haven't gone through it all yet, and I'm hoping it will). There are quite a few other omissions and mistakes too in the Incrementum Digital course.
So I'd recommend everyone, beginners and intermediate PPCer's alike, to first go through the Stephen Noch course, and to consider checking out the Incrementum Digital one afterwards to see if they can gain any additional insights.
Hope this helps someone.
@sammiefields22 do you have full version of Incrementum Digital i see it's missing a lot of content
