I use a level to transfer saddle angle from one bike to another which is using the same saddle. I try to remember exactly how the level was sitting on the saddle when I had the saddle adjusted perfectly by feel on the road, because saddle adjustments can go out of whack That's what one should use a level for. Yeek, that's awful, but isn't "That's for what one should use a level." worse? Knocks the scansion way off. Must drive poets nuts.

Anyway, to fix all that stuff mentioned in the ensuing discussion, take your bike through this process: How can I fitting my bike

Yes, probably having the nose up like in the photo could cause one to curve their lower spine, trying to keep the jewels from getting crushed. Number one thing for good saddle fit is to ride with the lower back as flat as is comfortable for that back. Then adjust the saddle to work well with the flat back. Be aware that flattening your back can increase proper reach. Some people ride with curved backs simply because their bikes are too small and/or have too little reach. The big deal with the flat back business is explained here: Riding Position Discovery
