World Boxing Super Eight: fight splits

[Crease]

So thus far, The World Boxing Super Series or "Super Eight" as most of us have taken to calling it has been a resounding success thus far.
No pullouts, no injuries, no problems...

But I have been wondering (for a while now) how they have put such a massive project together. Reportedly there is £38 million pounds up for grabs in each tournament, but I wonder about each individual fight splits...
I haven't heard anything about the Groves vs Cox split, but I imagine it wasn't 50-50?

Anyone shed any light on this?

I haven't seen anything but I assumed the winner would get more.

I am pretty sure its based on winner gets more
