+1.... Tighten the bolt ...if the leather "bottoms out"(!) on the rails. Otherwise just ride it....
So long as it's not bottoming out on the rails, sag is good - it allows room for your nutsack .
Your sitbones are located very close to the rigidly-supported back edge of the saddle - the sag in the middle of the saddle does not really affect the sitbone position or angle.
I always put a plastic bag over it when it's parked outside. Not because I'm afraid it would get waterlogged, but because I would be devastated if someone stole it.... plastic carrier bag stuffed under the rails is handy to cover it when parked if it's likely to rain but I've never had one damaged by water and I've ridden nothing else since 1977.
