Swann was England's most successful bowler with 3-92
England's Graeme Swann defended the controversial umpire review system after three lbw appeals were referred on the third day of the fourth Test.
The off-spinner collected two wickets via third umpire Daryl Harper as the West Indies finished on 398-5, 202 runs behind England's first-innings score.
Swann said: "While it's there we intend to use it to our advantage.
"In Jamaica we weren't happy with it, we thought were on the rough end of a couple of decisions."
The International Cricket Council (ICC) has sanctioned a trial use of technology during the five-Test series in the Caribbean, although both teams have, at times during the series, appeared confused by its regulations.
Opener Devon Smith and middle-order batsman Brendan Nash were both dismissed via referrals from on-field umpires Aleem Dar and Russell Tiffin off Swann.
And Shivnarine Chanderpaul was controversially given out to a ball which Hawk-eye predicted would have missed the stumps off James Anderson for 70.
Third umpire Harper does not have access to television tools such as Hawk-eye or Snickometer and his role is as an advisor, with the on-field officials authorising the final decision.
However, Harper's advice at the Kensington Oval prompted West Indies coach John Dyson to speak to match referee Alan Hurst during the final session of the day.
"It's a system that will have people arguing over it but people have always argued about lbw," Swann told BBC Sport.
"It's not very nice when a decision has been given and it's referred - you desperately don't want it taken away from you.
"As a bowler I have been complaining for years about lbws I don't get. The odd one here and there I'm not going to complain about."
