Hello Franz,

Thanks for your comments.  Let me see if I understand you.  Because the rating
scale goes from like 2000-2800, but the mhz varies from 133 to 550 or so,
there is too much variation in mhz relative to rating and that will skew the
results.  I think that might be right, if that's what you mean.

Example:
Rating  mhz     R/mhz    R/log(mhz)/100

2200     200     11.00      9.56
2200     300      7.33      8.88
2200     400      5.50      8.45

2450     200      12.25    10.65
2450     300      8.17      9.89
2450     400      6.13      9.42

2700     200      13.50    11.73
2700     300      9.00     10.90
2700     400      6.75     10.38
2700     500      5.40     10.00
2700     600      4.50      9.72

One can see the benefit of your suggestion.  Using R/mhz, it's about equivalent
for an account to get 2200 using 400mhz as it is for one to get 2700 at 500mhz,
which is clearly wrong.  But r/log(mhz) method handles it correctly.  It also
handles the case when comparing 2200 at 200mhz vs 2700 at 600mhz.

Would there be a better formula to use, or is that sufficient?

With respect to TCB, I made the judgement that it is a mature program, and
doesn't really fit in the experimental or "green" category.
