omg I am loving these graphs!
I need someone to take my egg weights and make it into a graph at the end haha
I used the calculator on my computer. Didn't have to figure the percentage...just hit the "percent key."
I added up the "before setting"
weights of each egg in grams, got a total, and divided that number by the number of eggs. (
59.5 is my average egg weight in grams)
Then I put that
average weight into the calculator window,
hit the times key,entered 13 and hit the % key, the result equals the number of grams I needed the eggs to loose before hatch.
(59.5 grams TIMES 13 percent is 7.735 grams or 7.7 grams.)
I had to
then put the original average weight back in the calaulator and subtracted the "number of grams they needed to loose.
(59.5 grams -7.7 grams = 51.8 grams). Now I got the weight my eggs should be to do the best on hatch day, for these eggs, 51.8 or about 52 grams....
Time to make the graph
Mark a
point that correctly represents the ideal average weight on the chart for day one. (
for me, 59.5)Next move to day 21 and mark a
point that represents the ideal average weight on that day... counting down graph lines to mark the point correctly. (
for me 51.8) Draw a line to connect those two dots. You've made a proportionally correct "ideal weight loss line."
That made a graph with the ideal weight loss line beginning at the "before setting weight" point on the chart day one, drawn to the "21 day" point.That bottom point is figured as original weight minus thirteen PERCENT of original weight in grams. Now you just compare your obtained weight-loss to the ideal weight loss line you made marking points on the graph for your actual loss. If you are loosing too many grams on average when you check...you may add more water, If you are not loosing enough, compared to the the ideal for that day, you may adjust by lowering the humidity available.
It would be much easier if all eggs were the same weight, but they are not. The best
estimate is an
average of all the eggs (in grams) ,
minus the
about thirteen precent of their "average setting weight" in grams. We lock down at day 18-19, but I am uncertain that ALL the 21 days' weight loss needs to occur by day 18. It is just we won't know after lockdown. (that is too late to effectively alter humidity to effect much change anyway.) If you draw your ideal line correctly, on day 18 the chart will give the ideal weight for that day, even though you draw a chart to day 21.
There are charts for free in the learning center, and some plain ones online.
When I first started trying to understand the graph, I had to be careful not to confuse "grams" with "percentages." Apples and Oranges. That is why I kept saying "average weight in grams."
Anyone wanting to correct any glaring errors here, I'd apprecite that.
