I think your attitude is abhorrent.

Cheating matters. The purpose of going to college, or recording track times is for measurement and comparison. Allowing cheaters isn't just cheating yourself, it devalues the meaning of the measurement. It is inherently selfish and shows a lack of ethics that is detrimental to society as a whole.

It absolutely is not "only short changing yourself", as it also has very real, direct effects when a cheater displaces an honest hard-worker for a job or college acceptance.
