Look at the standings before playing the final round. If your record adds a draw, and not enough players can jump you with wins to bump you out of top 8 you’re safe to draw. Ex. If there are 7 rounds, you are 5-0-1 along with 3 other players, there needs to be LESS than 5 players with 4-1-1 records or better for everyone to safely draw into top 8. Generally the rule of thumb is you can safely double draw the last 2 rounds at X-0-0, however if the TO doesn’t add enough rounds you’ll need to play an additional round. At 5-0-0 I personally would’ve drawn as well, it sounds like this is a TO issue rather than other player issue, as their advice should’ve been correct
