Are the A1 apertures smaller or bigger or the same as the small aperture on an A2?

Just curious.  I know that the A1 has 2 apertures, same size but one is higher for longer range shooting.   But from what I understand it's the same size unlike the A2 how it has 1 big one small, the small being higher.  But my original question is what I'm wondering .  Size of hole in comparison the A1's to the small ap on the A2.  You get me?

They look about the same. The A2 might be a tad smaller.

Measured 2 A2s .068in.(small app.)
Measured 2 A1s .078in.

Thank you!!!!  You guys get a cupie doll!!!
