Yes, it is acceptable. For someone with a bachelors in CJ you should know this. According to the officer your peak speed was 53. When your vehicle came to a halt your final speed was 0. In between, you also traveled at 50 and 45. Indicating any of those speeds is correct and within the officer's discretionary authority. He gave you a break by indicating the lower speeds.
However, if you are an absolute stickler for accuracy, go to court and point out that the officer failed to list you peak speed. The judge is a reasonable man and no doubt will allow the officer to amend the citation and correct it to reflect 53 MPH instead of 45.
