The Fiji women's sevens coach wants to see improvement this weekend in Atlanta, but says his players are still adjusting to being full-time on the world circuit.
The Fijana are eighth in the series standings after two rounds and play Australia, France and Spain in pool play in the USA.
Their build-up hasn't been ideal, with another two players left at home for disciplinary reasons.
Iliesa Tanivula says it's still a new thing for Fiji to be playing international teams each month, but says the players are embracing the challenge, even if they still have a long way to go.
"There's no easy team in the series now. Spain, we played them in the bowl final in Brazil and of course Australia has been our biggest hurdle at the moment. It's good - we've played a few times - and the girls are loving the challenge. If we can keep improving as we go on it will be good and of course France are a well drilled team so it's a challenge for us to get up and try to knock them over."
