A football field marked with the hash marks at even thirds spreads the field error across the entire field. That gives 28 steps sidelines to hashes and 28 steps between. States like oklahoma still use even thirds of 28/28/28. If you go to a college stadium in OK that is also used for high school football, you will see both sets of hashmarks.
Texas uses the NCAA football handbook which puts the entire field error between the hashmarks, hence the 24" step (20 steps) between the hashmarks on NCAA fields.
