I understand what you may be driving at but we are talking Amaya technology. Bobbin tension vs threadfeed can/will have a definite effect on the Amaya's "auto acti-feed" system. To say that it will change or have an affect on trim length when the top thread is fed by the threadfeed motor and computer technology.....well.....not directly anyway or by creating a given consistant trim lenght. Loose bobbin tension may create a loose bobbin/thread condition that will allow the trimmer to slide over the top of the bobbin/top thread, partially cutting it and then the grabber breaking it which may look like a long tail or missing the trim altogether....but really auto acti-feed is what would be noticed with false thread breaks or false bobbin breaks. Older non-Amaya technoloy with all the tension knobs might have a greater chance for trim length changing from bobbin tension, but even then loose bobbin/tight bobbin tension still gives you problems not associated with a regulated trim length of the top thread....
