I don't know if anything like this has been shared before, and if so, i will delete my post.
I had a lot of questions about humidity, and there are LOTS of opinions. What moisture content, how much water, should i dry incubate, is my moisture meter calibrated correctly, is the air cell big enough, will i drown my chicks etc.
But a pretty universally acknowledged fact is, that an egg should lose between 13 and 15 percent of its weight from day 1 to 18
So i made a (pretty bad, but functional) spreadsheet to determine the optimal weight of eggs during incubation. Just put in the average weight of all your eggs on day 1 in the sheet, and then weigh them again when you see fit, and plot the average weight of the eggs on that day into the sheet to see if it is within range. Both as a number, and a visual representation.
If it weighs too little add moisture, too much, remove moisture.
You need a scale that can measure to within 0.1 grams like a letter weight. Cheap on eBay or Amazon.

Here are illustrations, with fictitious numbers plotted.
