It depends on the recipe. Some call for equal parts water to vinegar, others call for more vinegar than water. Some recipes include sugar, others don't. I'm guessing it is the vinegar that causes that to happen and the ratio of water:vinegar.
And, you don't want to know how long eggs can sit in a warehouse before they make it to the store. To check the freshness of your eggs, submerge them in water (I use one of those plastic tubs when I wash eggs). The freshest ones will stay on the bottom, horizontal. It is not unusual to get some really fresh eggs and some older eggs in the same carton.
I pickle my eggs in beet juice. Put the juice in a big jar, add the eggs and whatever amount of vinegar needed to cover the eggs. I like them, even rubbery!
I know you said that eggs are good for 45 days. Would the date on the carton be 45 days from when they were laid? I don't usually check my eggs, but I do see them stand up in the pan sometimes. I don't pay much attention to it. My husband says that if they actually float, don't eat them. LOL
I just checked my eggs that I bought 2 days ago at the discount grocery. They lie perfectly flat in the bottom of the pan and the exp date is 8/26/13.
