would you continue my step 3?

I am lazy to do next.
Sure but I don't know this site. It may calculate results a bit different. It looks like another Bitkong child but i can't find it. Throw link and I'll help you.
Great work @Tytanowy Janusz

It would be great if you can explain to them it provably fair works on that site and prove it is not scam.
