Man, you really need to quit quoting statistics if you don't understand them.
Table 1 of your link shows the statistics of the respondents to the survey vs the US industry.
Among the respondents, the truckload carriers are under represented by 27%
Other / Specialized carriers are over represented by 32%.
Last time I took statistics, if your sample is off by 30%, your numbers aren't worth the ink to print them.
