hypothesis

A guess made by someone with a PhD.

In common usage, the words hypothesis, model, theory, and law have different interpretations and are at times used without precision, but in science they have very exact meanings. A hypothesis is a limited statement regarding the cause and effect in a specific situation, which can be tested by experimentation and observation or by statistical analysis of the probabilities from the data obtained.
It's not just a guess, it's a hypothesis.

7-level

A small screwdriver with a fine tip and having a pen clip attached, making it capable of being easily carried in a shirt pocket.

This word originated with US Air Force electronics technicians and is derived from the skill level digit of the Air Force Specialty Code (AFSC) (example: 30670) where "7" indicates an advanced technician. The idea being that this small screwdriver is used to make precision adjustments to circuit board components such as trim potentiameters that require a higher level of technical skill to perform.
The 15 hertz circuit on the TACAN is a little off. Could I borrow your 7-level to adjust it?
