Delta could also help themselves out by allowing MLOA to be more granular - by allowing pilots to log it in hours or half days instead of full calendar days. If someone is going to pre-post military leave and must ensure crew rest (in either direction), they often must post an extra day at the front and back of the actual duty. If they could instead say that they'll need to be in crew rest by (for instance) 8pm, that could free up the rest of that day for Delta duty.
