Some stuff that may be of assistance to you now that there are POV
*****************New for 1998***************
Equation for the new hot off the press chart of pumpkin wt vs circumference that I provided to Langavin for his book.
Not near as accurate as over the top but good for quick day to day gain.
# lbs = 0.001517 times (circumference) to the power of 2.61374
ie a 39" pumpkin would be 21.8 lbs
a 146" pumpkin would be 688.7 lbs
For you guys & gals out there who need my more accurate over the top equation
it is as follows.
# lbs. = 0.0000795 times (sum of the three over the top measurements) to the power of 2.76
ie a 96" pumpkin (over the top) would be 23.5 lbs
a 350" pumpkin would be 835.6 lbs.
A chart for this is also in Don Langivin's Book #2
Remember these only give estimates and every pumpkin will weigh different on the scales. However I believe that Zehr's 1061 lb pumpkin in 1996 was within 2.8 lbs (0.26%) of that predicted by the over the top equation (that was created in 1993). The new Feb 1998 circumference equation would have predicted that Zehr's Pumpkin would have weighed 1122 lbs or would be off by 61 lbs or 6%. You see why I say that the over the top measurements are more accorate.
Wish you all the best this year
Bob.
