Do you think my blood pressure is high or was the reading at the doctors bad?

Long story short:

Past readings have been 137/75 - 140/75 (pre-high)

Most recent reading was 144/80, which is high

HOWEVER

1. I was seated on a table with my legs not touching ground (known to cause a bit higher readings)
2. They used a regular cuff and my arms measure like 16-16.5 inches, regular cuff is made for 9-13 inches max
3. White coat syndrome, aka most people test higher at the doctor's
