Not sure what brought about this thread but yeah, talking about units when you are making 20x or 30x your "unit" doesn't have a real practical sense to it.
When it comes to the tracking, I would do a few things. I've been known for meticulous tracking, and tracking far more than just the profit and loss, including closing line comparisons and other info...including a unit chart to show where I was and where I am now. I never changed the risk size though.
I would track that wild bettor a couple of ways. First, set up different tracking for different bet sizes, which isn't very good overall. Second, perhaps display an average bet size with average odds, also not very good.
Or, to avoid picking apart types of play and types of bets, you could show a record, average bet size, and then the all important ROI.
Between ROI and charts showing the overall units and/or record since the beginning you can really get the picture of what is going on. You can see the variance in risk and the sudden change in the "units" with that 20 or 30 unit bomb win or loss.
Is there someone we need to audit, Stormy?
