[quote]"Dave,

These are observant and excellent questions, which go to the heart of the system Doc invented for 'Equalized/Normalized/Adjusted' (or - 'comparing apples to apples', to use another metaphor).

Here are a few core concepts to always remember:

1. After the raw data is finished being adjusted, today's race is NOT being run at today's track: it is being run at a mythical Sartin Downs. Read that again, please.

2. All pacelines are adjusted as follows:
a) Equalized to today's distance, by applying a 'Par Gap' differential between a base time for each distance/surface and the raw final time,
b) Normalized by an InterTrack Variant (ITV) supplied by TrackMaster which serves to adjust final time from different tracks/distances/surfaces to today's circumstances,
c) Adjusted by a Daily Track Variant (DTV) which serves to adjust final time by how fast or slow that day's average surface times were compared to a par for that surface..."[end quote]

Ted::

As to your above post, I have on more then one occassion commented on my distrust of the adjuted times especially as it pertains to the use of the Match Up Methodology. Many times the call times are adjusted to times that are either unrealistic or certainly greater then the pp's show possible for the contender. The adjusted times seem to work great with the BLBL output although I have never compared using vs. not using. I wonder if anyone has in fact compared the BLBL results using adjusted times vs. not?

Thanks,

Robert
