• Added a configuration option to control the display of tournament equities (Window: Preferences: Equity Display):
  • Total Regular Prizes: This is the "classic" mode and displays equities as a percentage of the tournament's total regular prize pool. This total excludes bounties, so bounty calculations have equity totals of 100% + #players x bounty.

The normalization factor can be displayed by hovering over the hand tab header.
