I don't know what to tell you, I cut and pasted the data from covers and input a formula into excel to find all home teams that won and were +100 or more.
Wasn't knocking your figures, just can't believe there was such a difference. I used actual dollars won/lost from my own books for those years. I had a similar difference off Phil Erwin's books. I'm either doing something wrong, or something right, as the case may be. I know your figures are accurate, I bet them blindly, no filtering, etc. Shopped like hell, but that wouldn't account for such a disparity.
