When it comes to AOV, I created an app for my phone (Turbulent Turtle Optical Tools) that when I put in the published FOV at minimum mag and the FOV at maximum magnification, the minimum and maximum magnification and specify a magnification, it shows me the AOV at minimum and maximum magnification and the FOV at the selected distance.  I also created a spreadsheet in which I have accumulated the information for about 120 different riflescopes using their published values.  The spreadsheet does the calculations and shows me lots of great information.
For the Comp, I had the published values from a few years back and I went to their website to make sure I had the correct values.  They no longer publish the FOV values for the Comp.  Undeterred, I downloaded their propaganda sheet (2024 catalog) and the values were in there on page 33. I use the metric values when they are there as I find them to be more accurate and consistent across manufacturers, but the feet/yard usually agree with the metric.  So they say 15-X to 55X, with an FOV of 2.3m/100m @ 15X, and an FOV of .6m/100m @ 55x.  This translates to an AOV of 19.9° @ 15X and 18.9° @ 55X.  For 40X, that translates to 28.1 MOA or 8.2MIL.
For the Majesta, the published values in their propaganda for the Majesta are: 8X to 80X, FOV  of 5.45m/100m @ 8X, and an FOV of .545m/100m @ 80X.  (Notice how close the Majesta is at .545m @ 80X to the Comp at .6m @ 55X.)  This translates to an AOV of 25.0° @ 8X and 25.0° @ 80X.  Notice how consistent the Majesta is compared to others in AOV throughout the range.  For 40X, this translates to 37.1MOA or 10.9 MIL.
