Change the equipment and you change the context of the observation. I do not accept an impression from one setup as automatically interchangeable with an impression from another.
Identify the material, model, fit and condition. If you are reporting a measurement, identify the instrument, unit and method. A comparison that conceals those changes is not a useful record.
The Equipment Is Part of the Observation
A dog does not interact with an abstract test. It interacts with a particular person, surface and piece of equipment. I include the equipment because those conditions are part of what I am observing.
For an evaluation record, describe the equipment rather than using “bite suit” or “sleeve” as if every version were identical. Include the relevant construction, condition and fit, along with the task being assessed. Those details make the observation interpretable even when no numerical measurement is involved.
The Finnish sleeve study discusses sources of variation including grip, bite angle and sensor contact; its reported values belong to its measurement arrangement. That is a reason to report conditions carefully, not to turn its results into a universal pressure label for every dog or device. (Hyytiäinen et al., 2021)
Ask a direct question: what does this result tell you about the dog in this task, and what does it leave unanswered?
Respecting that boundary does not weaken the observation. It prevents the equipment from silently answering a question it was never designed to test.

THE READING RECORD
Supporting References & Further Reading
I draw on my operational experience and the Bite Chain discussion above. The linked research supports specific points; its limits still matter.
From my operational record
I have worked as an operational K9 handler since 2009 and have seen more than 44 dogs go through our unit's program. These articles draw on that work and the feedback I bring to our K9 specialists.
Record the equipment and measurement method. Personal sensation is not a calibrated measurement.
