Because the measurement of such distance is prone to error as a result of the curved and non-linear nature of the surfaces, error in the premises of + 3cm was entertained, with this, J9 & J8, J11 & J12, J16 & J18, and J20 & J21 were categorised as systematic joints with average perpendicular distance of ~62cm between them others are non-systematic joints (Table.
When the zigzag orientation of J5 is considered the egg becomes totally distorted but with J9, J10 and J11 nearly perpendicular to J5, the egg and 0 tip geometry shows that this systematic joints do not intersect with J5 at any point (fig 6.
