@clementdupOz just FYI, the reason I only bet a little, is because the description of this market specifies "without style control". When style control is off, 2.5 pro still wins. and 3.0 is likely to be a lot higher.
@clementdupOz they now provide a direct link to the "Without Style Control" setting. See here for the current ranking the market resolution will be based on:
