You're taking raw data from trackers and entering it into some other system for display.
Why are you inserting a person fat fingering data into the mix?
Make a program/script/application to convert and upload the data. It will be faster, more accurate, and solves the problem of needing to design a form.
If you absolutely must have a person involved, build your form based on the data the person is using.
If the person is looking at output that includes start location, end location, start time, and end time, those should be your fields. If the person is getting a geo coordinate and completion time in milliseconds, that's what the form fields should be. Converting those inputs into the output of the report should be the responsibility of your application.
You're building a super specialized app for a single purpose/event. The KISS principle applies in spades (KISS = Keep It Simple, Stupid).
