The -803 looks funky, but everything else seems OK. If memory serves me correctly (per Quarq) any pre-post delta of 50 or less is within spec. I think you are OK. Remember, your manual calibration should be with cranks in 12/6 o'clock position. I always put drive side at 6 o'clock.
EDIT - if new, it takes a few rides for the zero numbers to settle in. Quarq guy told me getting up out of the saddle and doing a few hard sprints can help speed up the settling in process.
