Bearing number

So, I have a replacement hub from kind member MadHonk. I had to swap out a pitted race, but cones on this one were fine. Now a question about bearing numbers for the collective genius here. 13 balls came out per side in both my destroyed hub and the replacement hub. I reassembled the new hub dry and without the grease dust caps. Looking at the bearings in each side, they sure looked crowded together if not touching.

I have always read that proper number is whatever fits minus one. I took one out on each side to look at things and it looked more “normal”. Who am I to question the engineers, but these hubs have a long history of bearing problems. These are small 5/32” balls FYI. Bearings loading against each other rather than cups and cones? Thoughts?
