I appreciate the feedback! I'll try to respond to each point as you made them.
The amount being in Oz was 100% just a testing/flavor thing and not at all supported by math. The system is pending enhancement anyways, but then I may math out what the actual numerical values would be. Possibly. I'll always choose fun over reality in my mods and the reality of fetishes like cum inflation haven't really met reality, so I may just remove the oz part and leave it to imagination.
The consent system is fairly rudimentary right now, but should be using a new check function that will check obedience, loyalty, fear, lust, etc vs the request to add a lot of other factors and variety into the system. It is fairly flat with a basic check right now, but until I work the kinks out on that I will recommend checking their loyalty and obedience. That is the biggest factor at the moment, with Loyalty far over Obedience. Keep in mind that just because they accepted you as their master (no captured effect), they may not want to willingly risk their life for you yet!
The "secrets" are revealed in the stats tab, though v.07 is expanding on that even further. The Dimensional Crystal 2 will allow you to shorten the time down to a single day pregnancy if you want and it also compares the maximum potential stats from the mother/father and will give the baby the stronger of the two. That means you could breed hyper-intelligent orcs or any other weird game-breaking offspring you desire. All that to say...it is very game-breaking, but hopefully fun! It (hopefully) will provide either a different game-play style entirely (using the Breeder Specialization) or, like you said, add additional game-play options for after the main story.
Regarding Cali - I'll work on patching that for v.07. That would be immersion breaking
