Response to your edit:
Edit: Earlier you said we should stop talking about whether you can cheat or not. But talking about whether you can cheat is exactly the same as talking about whether the site is provably fair. When you say "this site is provably fair" you are saying "there is no way we can cheat you without you being able to notice". Changing the thread title to be "99% provably fair" is meaningless. Nothing is 99% provable - it is either provable or it isn't. Just like you can't be 99% pregnant.
The fact is your claims have not been proven, i have asked you to prove what your saying, but you have failed to do so.
You are no different then the house, if you think you can cheat the system then DO IT.
Once you have done that then you can say its not provably fair.
Or like i have asked before tell us some other way if you are so experienced in this field.
We would love to hear from you about how to take it from 99% to 100%
If you care like you say you do for the community then prove you can cheat the system, or tell us a different method.
