You can't determine the alcohol content simply by measuring gravity. We need more information.
Let's try to determine the alcohol by volume in your "best" result beer. For starters, it has gravity of 1.032 which translates into 83 grams of sugar per one liter of beer.
Tools we need to calculate the alcohol content:
1) Fill the pycnometer to appropriate level and determine the weight of the beer
2) Subtract the appropriate amount of sugar from that result
3) Use ethanol-water density chart to find the weight of ethanol
4) Use formula to convert alcohol by weight into alcohol by volume
1) You can find a lot of information on the internet about pycnometers and how to use them. Basically, they are used to determine the density of the solution. Let's say you have 20mL pycnometer. You have to fill it up to a level marked on the pycnometer and find the mass of the beer. Suppose you got the result of 20.02 grams.
2) Since we are dealing with very small amounts of sugar, we can assume that the volume of beer would stay the same if we removed it(*). In 20mL of liquid there would be 0.02 * 83 = 1.66 grams of sugar. We are going to subtract that from result obtained in first step. To find the amount of sugar in 1L of solution I used this calculator:
3) Subtract 1.66 from 20.02 grams. This gives you 18.36 grams. So, the density of water and ethanol mixture (since we removed sugars) is 18.36 / 20 = 0.18 g/mL (notice that we are using milliliters and grams which is OK). Suppose that you did your measurements in the ambient temperature of 20C, using ethanol-water-mixture density chart we can see that the alcohol by weight is 42% (**). Use this chart:
4) Using ABW to ABV calculator we can see that alcohol by volume is 52.5%.
(*) You can dig deeper to see how to adjust for the error when subtracting the mass of sugar from the mass of solution but as I said since the percentage of sugar is very small it is not going to make a big difference in calculation (because volume stays almost the same).
(**) Don't be alarmed by this number. It is possible that the very first results you got were this high in alcohol. Since I assumed there was 1 liter of your first results this is what you get. In reality it is more likely that there was like 100mL of this strong stuff.
