The explanation is simple. A medium bore (7mm to 30 cal) has a lot of powder for the bullet weight. Some have a 75/25 ratio of powder to bullet weight. the faster bullet produces the total recoil over less time. the big bores have a much more even powder to bullet weight ratio some times 50/50. The bullet produces inertial recoil that cant be altered except by adding or subtracting weight. and the recoil produced by the powder is the only thing that a brake can work with.
The speed that the weapon recoils is called recoil velocity. medium bore rifles typically have high recoil velocities because of the rifles weight and the amount of powder used. Big bore rifles normally done weigh more, and the recoil velocity is slower (More of a push as described) the faster the rifles recoil velocity, the more "Felt" recoil.
so it is not uncommon for big bore rifles to be more pleasant even though they have more total recoil than a small to medium bore rifle.
The time it takes to deliver the total recoil is the felt results.
Recoil velocity is one of the main culprits that cause retinal detachments in shooting sports.
Most of the rifles that I feel needs brakes, are the big 30 cal and the 338s. I don't have a brake on my 416 even though it has almost 80 ft/lbs of recoil. One of the worst felt recoil rifles I have is the 30/378 in a 7.5 lb rifle.

I'll comment on two points you raised in this post.
1. You mentioned retinal detachments. I have never had a retina detach but had three torn retinas before my doctor started probing my habits and when he came to my love of my 300 Win Mag and my frequent trips to the range where I would usually shoot 40-50 rounds per range session. He said I was crazy to be subjecting myself to that much and so frequent recoil. I cut way back on my shooting of heavy recoiling rifles and voila! No more torn retinas!
2. You also mentioned the 30-378 Weatherby round and it's inherent recoil. No kidding! I had a Weatherby Mark 5 in 30-378 a few years ago that LOVED the Nosler 180gr BT bullet and was amazingly accurate out to 1000 yards. BUT!!! The recoil was so ferocious that it just wasn't any fun at all after about 7 rounds in a day. Also my nervous system would get jangled kind of like being punch drunk and my accuracy would go south about that time. LOL
Needless to say I sold both rifles and now shoot kinder and gentler recoiling rifles but still abhor a brake and won't even permit myself to be anywhere near the firing line when someone at the range shows up with one.
