|My 2 cents. The inline anchor reduces the overall load on the anchor itself, as it would split the load, (say 500lb), between the two anchors (250lb/per).
Setting the anchor where the rope makes 45 degree bends, the 500lb of force on the rope, both anchor points will see a 500lb load, effectively doubling the load on the anchor.
Rapping doesn't generate the very much in the way of shock loads usually, but in a TR situation it is more likely, though can be avoided with a proper belay free of slack.
