Hi!
Also für Holz hätt ich da was:
Spinewerttabelle :

Spinewerttabelle für 26 inch (660,4000 mm) Abstand der Pfeilauflagen und 2 lbs (907,1847 g) Gewicht

Bei Carbon fehlt mir jegliche Erfahrung(+somit auch Tabellen)--sorry!

Die Formel für Holzpfeile ist ganz einfach, es wird die Durchbiegung eines Schaftes gemessen der im Abstand von 26“ (26 Zoll = 66,04 cm) auf dünnen Lagern aufliegt. In der Mitte wird er mit 2 # (2 Pond, 2 lb bzw. 907 Gramm) belastet. Mit der gemessenen Durchbiegung kann dann der Spine errechnet werden. Nach der Formel: Abstand / Durchbiegung = Spine, 26“ / 0,5“ = 52 # oder in Deutsch 66,04 cm / 1,27 cm = 52 #
Das stimmt aber nur für Holzpfeile, bei Carbonschäften wird der Spine in 28" Abstand und mit 1,94 # gemessen, darum wird bei Carbon auch der Spine nicht in Pound angegeben sondern die Durchbiegung in Tausendstel Zoll, zB 500 bedeudet eine Durchbiegung von 0,5 Zoll.
