Could someone post Len Stellpflugs´ and David Martin´s 2005 formulas (4 terms) or Len´s eMail address?

I need the latest circumference and the OTT equations.

Thank You!

i hope this is what you need.

No, I don´t need a .pdf file or another table but the Excel formulas:

I found this, but only the 2001 equations:

Now I need a update to 2005.

Thanks.

Sorry, but I don´t need a acrobat reader.

I meanwile found the formula for the OTT estimator:
=WENN(((0,0000217468*E6*E6*E6)-(0,000932949*E6*E6)+(0,26066*E6)-9,825656) < 0;0;((0,0000217468*E6*E6*E6)-(0,000932949*E6*E6)+(0,26066*E6)-9,825656))

I still need the formulas for the circumference method!

Please help me!

From Leonard B. Stellpflug, Equations for January 2005 Weight Tables (by David Martin)

Over-the-top Equation (2005)

Weight = -9.825656 + 0.26066T – 0.000932949T2 + 0.0000217468T3

WHERE “T” is Over-the-top TOTAL INCHES


Two Circumference Equations (2003)

Up to 120 inches:

Weight = -3.94723 + 0.113638C + 0.01073C2 + 0.000159C3

Over 120 inches:

Weight = -487.925 + 10.19604C – 0.05769C2 + 0.000309C3

WHERE “C” is Circumference in INCHES.

Hey! Awesome! Two equations....!

I'm glad to see the "piecewise" (more than one equation)
approach. I've been harping on this for some time. That is,
don't sacrifice the accuracy of the smaller fruits as you
put data in for the new larger fruits.

What would be cool is a piecewise equation for OTT, with
perhaps 3 pieces:

an equation for 0 to 250 OTT inches
an equation for 250 to 350
another equation for 350 and above
