Apologies if I didn't clearly state my goal/concern: I am not looking for
the exact same scoring - I am looking to explain scoring differences.
Deprecated components will eventually go away, time moves on, etc...
etc... I would like to be able to run current code, and should be able to -
the part that is sticking is being able to *explain* the difference in
results.
As you can see from my email, after running the different analysis on the
input, the output does not demonstrate (in any way that I can see) why the
fieldNorm values would be so different. Even with the different analysis,
the results are almost identical - which *should* result in an almost
identical fieldNorm???
Again, the desire is not to be the same, it is to understand the difference.
Thanks,
Aaron
