Hello AHOYBRAUSE,
Sorry that it took us so long to respond.
The calculation is correct, sportsbet wager contributes 50% to the total wagering requirement for the freebet bonus. Moreover, only bets with odds of 1.5 and above are considered into the calculation.
We pulled your betting log and if we may try explain to our best without violating your private data, it is correct that you wagered in total as you mentioned above. A couple of the bets though were bets with odds lower than 1.5 and they can not be counted as turnover. The rest of them are counted with 50% cap and it brought us to the same rollover number as you mentioned.
We are sorry for the confusion you experienced. But you can read more about the details of freebet requirements
on this page, and please don't hesitate to reach us if some or any part of it is not clear.

So you write 10x is the wager requirement but actually it's 20x when only 50% of the wager count. You think this is normal?? On no site I ever played I saw something like this. Why would you even write 10x rollover when it's totally not true? I mean we have the prove in black and white now.
Another fun fact, just to finish this up, I know you have added these rules AFTER I made my recent post, basically in the last few days. I know this because I read all the rules under
https://bcgame.nz/help/bonus , and these were 100% not added yet. But yet, just what I expect from BC.
