OP, I can't help but wonder the first time I read that request [marked in bold], which grew stronger by each time it being repeated. May I ask what purpose does it serve? To ask the casino to provide each bet with PF information? Certainly... well, hopefully it's not to make the request daunting --borderline impossible-- for them and/or anyone who oversee this case and would validate the evidence? You realized that you're requesting a PF verification for each bet, for --by your own calculation-- 4,700+ bets?
We will ignore the data given by betflexi at this point, because what I am interested to know is your reason and what's whirring in your head when you're for asking PF for each bet, thus the applicable numbers will also be what you had on your mind when you asked for it.
Their PF was convoluted and I want to review it. As I said I started flipping my bets after making a few losing in a row and this had a few wins in dice. I want to see if there's any pattern to their PF because they were generating the numbers beforehand. It made claims that it's provably fair but the user is unable to control their seed but they're able to manipulate all future bets with a randomly generated number for each bet. They do not use a nonce.
On that case, and on normal logic, it'll be better and feasible to ask for their verifier, the platform where players can check each of their game. Actually, it'll be more precise to say that it is what should be asked on every question about PF, so I still can't see the logic behind asking them to provide verification on each bet.
Nonetheless, I have to agree that saying they're provably fair and yet didn't give any method to prove the fairness is a bit... worrying. I'll inquire this on their ANN thread, given this topic seems to be beneficial for players future reference.

Let me try a different approach that I have in mind. Not sure if betflexi would cooperate with this idea, but it wont hurt trying. I'll need your consent to initiate this... shot-in-the-dark, regardless they'll agree to it or not: do you allow them to share your betting history to me, on for-my-eyes-only basis?
