Failure
Failure is the point where you cannot finish one more rep to the chosen form standard.
Failure: a practical example
For example, you cannot finish another full repetition with the technique required by your program.
Use it in your log
When you log your workout, keep this in mind: technical failure and inability to move the load at all are different stopping points. Clarify the standard.
Next, use the workout log to keep names, weights and reps in one place. Then check your progress across sessions.
