You certainly did it wrong.
it's not possible you have
Seat height: 87 cm -
Pelvic for clavicle 72 cm -
87 - 72 = 15cm
Do you have a neck and neck?

Seat height: ~ 87 cm + Pelvic floor 88 cm 87 + 88 = 175 cm height?
Should not you be 178-180 ??

his margin of error is so great that the result is 175cm tall and his head has 10cm (baseball) and neck 5cm


ask someone for help to measure if it is not too bad to draw conclusions like this
