Yes. Keep the lot board as the auction runs, track who bought whom and for how much, and the payout math settles itself off the final board. The purse is the bids plus any added money, less side prizes and expenses, paid out by your split to the cent. The bidding itself is yours to run; Swilkin keeps the book. Put a Calcutta block on your club's site and it publishes the pot and every paying place: team, buyer, amount.
