He must prove his proficiency since tickets are assessed based on your rate of speed.

If he were issuing tickets to baseballs, you would have a point.

I can tell you from personal experience as a LEO that you can estimate a vehicle's speed within +/- 2 to 3 MPH after a year of traffic duty.

Yes, it can be demonstrated and stand up in court.

If they were that good at it, then they would sweep down TWO cars when both are speeding rather than cutting the faster car loose.

Wrong. You can testify from personal experience that you, yourself, are able to estimate speed within +/- 2 or 3. You really don't have any idea how many of your fellow officers are able to do so with that kind of accuracy. Let's assume that 25% can't - that means incorrect or false speeding tickets 25% of the time. Should we be happy with that?

The problem here isn’t how accurate a LEO could be in estimating speed, but the potential for abuse in allowing officers to “make their case” solely on such grounds.

The problem here is potential for abuse. I’m not as worried about the 25% that can’t WAG a car’s speed as I am the 5% that would abuse the discretion to do so.

Gov’t - and its agents - must be kept in check. That is the essence of “limited government”.
