Randall and Allison finished fifth at the European Championships
The British synchronised swimming team's performance director Biz Price said the squad had "exceeded its targets" at the European Championships.
Jenna Randall and Olivia Allison delivered Britain's best result at a European event since 1995 with a fifth-placed finish in the Duet final.
Price said: "We exceeded our targets despite the fact we've had athletes returning from injury.
"This week has seen another step up in our performances."
Randall and Allison recorded a score of 90.300 - 8.400 behind gold medal winners Russia, who were followed by Spain, Ukraine and Italy.
Meanwhile, the eight-woman British team, competing in the team event for the first time, secured a total score of 87.10 to finish sixth in the final of the free team event.
Price added: "Our technical performances still need to improve as we close in on 2012 but the free programmes have exceeded expectations and are ahead of the curve."
