Based on what I have seen however, this is not the case and the spread is larger than 1 or 2.

Without benefit of seeing how you arrived at your conclusion, I can only offer the following two points.
1 - Likely, the following is what you read on their site.
"Class Rating
Class ratings are on a scale from 30 to 130 reflecting the difficulty of the race. A top class (minor Stakes) race might have a class rating (abbreviated CR) of 100; a $10,000 Claiming race might have a CR of 70. By comparing the CR of today’s race and the CR for each horse’s recent races you will know if the horse is moving up or down in class ¾ that is, if he is in an easier or more difficult race than he has been in recently. The calculation of class rating includes a weight for the track so you can compare class ratings between races at different tracks. An 80 at Aqueduct is equivalent to an 80 at Belmont and an 80 at Philadelphia Park. A horse that has been successful in races with a CR of 90 at Churchill Downs should be competitive in a race with a CR of 90 at Aqueduct.
Class ratings are given for each race, and several class ratings are shown for each horse, including the ratings of his last three races, an Average class rating, his highest-class rating, etc. This allows you to judge whether a horse is moving up or down in class. That is, whether this race is more difficult or easier than the races he has been competing in recently."
2 - I have been using Trackmaster for almost 15 years now on a daily basis and I find their product to be of good quality, reliable and informative.
If you don't mind taking a minute to comply, I would be interested in seeing how you arrived at your conclusion.
