This is what bet365 messaged me about under 4.5 for barboza vs lee
Dear Mr
Thank you for your Web Message in relation to the settlement of your bet on the Barboza vs Lee UFC match.
I'm sorry that your bet was not settled as you had expected.
I can confirm that for this match, the round was stopped after just over 2 minutes of fighting. As there was a stoppage in the 5th round, this would advise that in order to win, you would have had to place a bet of Over 4.5 as this was past the half way point in the 4th round.
Our rules can be located by going to the Services menu and clicking on Help. This will open our Help section in a separate window from which you should select Rules. You can then choose the required sports from the menu listed on the left hand side.
In line with our rules, for settlement purposes where a half round is stated then 1 minute 30 seconds of the respective round will define the half to determine under or over. As such, your bet has been correctly settled as a loser.
If you would like to clarify the markets that we have settled our bets on, our results service can be located on the Scores & Results menu at the bottom of our Website.
Kind regards,
Andrew Wa
