There is a segment on youtube showing a goverment airliner somewhere in europe overrunning due to a sudden bird ingestion in one engine. It is clear in the video they were unsure what to do.
Balanced field assumes a total failure (not feathered, for a prop).
It also provides a few seconds to recognize symptoms, make the decision, and execute the abort. It's really pretty easy to recognize cuz a total failure will produce big yaw...I don't look for ITT abnormalities, if the thing heads for the grass prior to V1, I abort.
A partial failure would still provide thrust, so even if you didn't abort you could still probably go flying. Personally I would abort for any sort of drama involving controllability, vibration, or multiple engine indications, without a lot of analysis.
