Caged bottom bracket bearing direction.
I had a heck of a time getting my bottom bracket adjusted until I removed the bearings from thecage
and put them back in loose.I thought I had the cage in right so maybe someone can tell me.
This side of the cage was facing into the cup.
This side was facing into the cone. Is this right or did I have it backwards?

The side with exposed bearings runs in the cups. Sounds like you had it right.

Looking at the closeup photo it looks like the center of the cage is chewed up some so maybe that was the problem

Looks like I had it in right so my cages must have been bad or at least one of them

This is too much. Here's the Official Park Video. I've always done it this way. YMMV

This side of the cage was facing into the cup. This side faces into the BB towards the other set of bearings. Slide this onto the spindle...
This side was facing into the cone. Is this right or did I have it backwards? This side faces the Crank arm to the outside of the BB. Put the cup over this.

Definitely "ymmv." He does a couple weird things (to me, anyway): installing loose balls on a lubed spindle before insertion in its cup and also mounting a drive-side crank arm to help his lock ring adjustment. He also uses 3-4 times as much grease as I would.
In general, I love his videos and matter-of-fact speaking/approach.

Agreed. Grease the fixed cup race, insert loose balls (I use magnetic screwdrivers) and use finger feel to bed bearings.
My old mechanic mentor always said you can't have too much grease on a traditional BB but it's dealers choice.

11 and 9 were different for me too
Robert, I had my 615 apart I think and with the 11 balls in the cage, it fit backwards compared to the 9 ball cage. It was a bit counterintuitive, but just dry fitting and spinning the spindle and cups in hand revealed it.

Loose are better than caged anyway.

When you put the loose balls in did you add the extra ball or two to fill the circumference? It requires more loose balls that it does with a caged unit.

This is the correct orientation of retained bearings in the cups. Remember this and you'll always get it right. From Vintage Campagnolo Super Record Bottom Bracket Review | Cycling Obsession
