This is why Losmandy dovetails are the best choice, solid bar stock machined correctly with no weak open bottom and proper support in the saddle during clamping. There can be no?metal fatigue leading to weak clamping and no?misalignment in the saddle if you use a solid bar dovetail.
The photo below shows a Losmandy double clamp D/V saddle with a Vixen dovetail made by Losmandy. Note the solid bar dovetail base is supporting the dovetail in the saddle properly aligning it for clamping. This is the way these parts are designed to work and why extruded Vixen size dovetails with long fins are inferior.?
