In looking at the Maine Pumpkins Excel growers diary spreadsheet, there are two formulas for weight, one based on daily and one on weekly. The first below is daily. My question is, does it make sense that the same OTT measurement result in different answers? I know they are very close, but is either "better" than the other. Seems the shorter one is easier.... At 150 OTT they are almost 4% different but at larger weights they converge. Just an observation. And before I go, let me say THANK YOU to the creator as I have been using this diary for several years now.
=IF(((0.0000203*E5*E5*E5)-(0.000638*E5*E5)+(0.206021*E5)-7.380555) < 0,0,((0.0000203*E5*E5*E5)-(0.000638*E5*E5)+(0.206021*E5)-7.380555))
or
=(POWER(E6,2.76))*0.0000795

First or second week of October will tell ya if your measurements all year made a difference...LOL...using the ailts 2005 circumference table versus OTT table my pumpkin is much heavier using the circumference table by 50 lbs...so I always say I'm somewhere between the two. Just guesstimates....but it does give ya an idea of what's going on.

Alexsdad, Could you help a first time grower understand how to measure properly. I don't think I fully understood 2005 table because the way I measured definately is not right because my pumpkin has to weigh more that what I am coming up with. Could you help with pictures or a diagram showing how you measure. My e-mail is pottery@logantele.com. I have 2 good sized pumpkins and I would like to do this right. Please help.

The first measurement is circumference - The technique for this is to measure as you would around a dinner plate.
The second (or third) is the Side to Side - Measure this by putting the tape measure on one side of the pumpkin so it touches the ground and then go over the pumpkin until it touches the ground on the other side.
The third is end to end - Measure by putting the tape measure on the stem end of the pumpkin so that it touches the ground, then go over the pumpkin to the blossom end where it should touch the ground again. Be sure not to include the "knob" at the blossom end in the measurement.
The SS and EE are basically a cross on the pumpkin lined up so that it goes from stem to blossom and side to side. If you were on a ladder and were going to shoot the middle of the pumpkin, the cross hairs would line up with how you want to measure.
Hope that helps or find someone with Don's book How to Grow Giant Pumpkins II as it has a diagram of what I describe.
If you tell us the age of your pumpkin and the measurements you are getting perhaps we can see whether your cc, ss, or ee are off because typically they have a reasonable ratio to eachother.
Goodluck and feel free to email or ask more here.

I thought stem to blossom end measurement was just a measurement between the two...not ground to ground.

Ground to Ground - Your pumpkin just gained a lot of weight :-)
Not sure what Mr D is getting at Walmart
