Sun in Aries 0° 19' plus Sun in Libra 24° 22' is equal to a Sun in Capricorn 12° 21' in composite.
That same Sun in Aries plus Sun in Libra 9° 1' is equal to a Sun in Capricorn 4° 40' in composite (I've never understood why Capricorn instead of Cancer).

I'm trying to calculate a midpoint between two different asteroids of two charts (so I have to do it manually), asteroid 1 is in Aries 23° 14' and asteroid 2 in Libra 2° 18', giving as a result a midpoint in Cancer.

I've tried it again with an asteroid in Libra of my chart at more degrees than the asteroid 1 to test, and I've got a midpoint in Capricorn.
I interchanged their places (a-b for b-a, I use Ebertin style) and it continued resulting in a midpoint in Capricorn.

Sometimes I use the table to calculate midpoints, and when I get a midpoint (for example) in Virgo, astro Ebertin shows it in Pisces, so I don't know how to calculate them correctly because I realized in some cases you need to plus 360° to one of these asteroids.

Jupiter in Leo 3° plus Asteroid in Scorpio 9° is equal to a midpoint in Virgo 21°.

BUT Asteroid 1 in Taurus 17° plus Asteroid 2 in Capricorn 21°, with the table I got a midpoint in Virgo 14° while Ebertin showed a midpoint in Pisces 14°.

it's because you always use the shortest possible distance between two points as the midpoint.
As I invision and feel it, it's the energies 'radiating' around planets/asteroids/points, which are meeting at the midpoint,
therefore they are stronger where they meet at the shortest possible distance, which can never be more than 180°,
so between Taurus and Capricorn it can never be in Virgo - imagine how weak the energy of those planets asteroids/points is there, in comparision to in Pisces.
You also don't use aspects bigger than 180°, because there is always one at the other side of the circle, that is stronger, because of the shorter distance.
