Jim,
Don't worry about the formating, the figures were clear enough. I frequently have the same problem when trying to post table-like messages.
While the results you get by adding 3 points to the Strub numbers are plausable, leaving them as they are is more likely to be correct. The reason for this is something I discovered when I used to make my own figures. Beyer once did a study from the DRF database and found that the average race winner has an improvement in his Beyer from his previous race by 6 to 9 points ( this is roughly equivalent to 2 or 3 T-Graph points). By not realizing this I found my own figures were begining to creep downwards. If one applies this average improvement factor to the assigned Strub figures you will find they are more in likely to be correct without adding the 3 points.
