OS, you are 100% right, given the right circumstances. People who play hundreds of games can only produce at best about a 3% or 4% ROI. That is a fact that I don't believe anyone can argue with.
But, if one is patient and only plays maybe 8 to 10 plays a month and only plays the best plays they can find a much higher ROI is not only possible, but should be expected.
The guy that trained me many moons ago only played college basketball. A good year for him was something like 250 winners and 220 losers. He only looked to be up maybe 10 or 12 units for the season. A small ROI was great for him.
I play much different. It is entirely possible for you and I to have the same positive dollar amounts at the end of the month, with the only difference being the ROI. I learned a long time ago that there is no better winning percentage than 1-0. I can turn that around and say there is no worse losing percentage than 0-1.
So when I talk about a ROI of 35%, please keep in mind that I'm looking at a whole different set of numbers. If someone plays enough games and has a ROI of 3%, they can make as much money as I do at 35%. Simple math....
I do have a question. As I'm researching this data I've run into a bit of a problem. The SF game today had Schmidt with an ERA of 6.00 while Armas had an ERA of 6.60. This would mean that Schmidt was the better pitcher. But the WHIP advantage belonged to Armas with 1.20, while Schmidt had 1.78. I will assume that you prefer the WHIP.
My wife, Mama Bird, actually has something she calls AHWG (Average Hits, Walks per 9 innings). We get this from the Dallas Morning News. They do not have WHIP in the paper and I don't know where to go and get the past results that include the WHIP, but Mama Bird tells me that the WHIP is nothing more than AWHG divided by 9. For example, the AWHG for Schmidt is 16.0. If we divide that by 9, we get 1.78, which was his WHIP.
With the above explained, again, I will assume that you're looking at the better pitcher being determined by the WHIP or AWHG. Is that correct? Once I get that answer, I can start summing up the data.
