I have the Vantage Select. I use the chart on the side panel and its set on 40 per the chart. Also I selected Proportional. I'm sure the system is actually working, I just want to be able to have braking best matched to the system as a whole. I can't measure the braking force without some sophisticated force metering which would be expensive and I certainly don't have or to have access.
If I had a method of determining whether the toad brake is not too soft or too hard, that's the ticket. If too soft, the braking under panic stop condition will still have excess stopping distance. If too hard, it might lock the brakes and the toad's rear could buck or start jumping side to side.
