I would have thought the manufacturers 'range' would be the green area of the chart.
I've never had tracking done, so may be wrong, but that's the way i would have interpreted it. The chart will show an acceptable range, and as OP said NSF tyre had hit the kerb that's now showing outside the accepted range.
No idea what the small numbers versus big numbers are. Maybe that is just the before paperwork, and they've not supplied you with the after readings. If they claim that is the after, then i'd be questioning why it's still showing as out of accepted range.
