What these people have told me is that each pin and bush takes less load as it gets further away from its first contact with the sprocket tooth and more pins and bushes come on to the sprocket. By the time it gets to the top (travelling forward) all the load that it has is the weight of the track across the top. This makes perfect sense to me, whether others can see it or not.
Just my 0.02.
I'm not sure that's always correct. If the pitch of the sprocket matched the pitch of the track chain then I'd buy into that argument.
Now imagine the situation with a very well (knackered) worn track chain. Obviously the pitch of the chain is now greater trhan the pitch of the sprocket, in this instance it would be the last of the contact teeth that take the load.
<Edit> I think I may have got that wrong, maybe it's the other way around, I'm trying to visualise it!
