When Raducanu was preparing for her return a year ago, she spoke about making a "fresh start".
Climbing almost 250 spots is impressive by anyone's standards.
In fact, her rise this year has only been bettered by three WTA players - Japan's four-time major champion Naomi Osaka (unranked to 59th), Australia's Ajla Tomljanovic (549th to 85th) and American Amanda Anisimova (359th to 36th).
The highlight of Raducanu's year was the British grass season.
Runs to the Nottingham quarter-finals and Eastbourne semi-finals teed up a heartening Wimbledon, which ended in the last 16 but further fuelled her "fire".
Raducanu skipped the Olympics and endured a difficult US Open swing, before reaching a fourth quarter-final of the season at September's Korea Open.
A foot injury halted her momentum, but she finished on a high by winning all three of her matches to help Britain reach the BJK Cup semi-finals.
"I know I'm a dangerous player," said Raducanu, who has earned £11m in her comeback year and is seventh on a list of highest-earning female athletes in the world according to sports business experts Sportico.
"I know no-one wants to pull my name in the draw.
"I take pride in that and I'm looking forward to hopefully staying on court longer next year."
It has been far from smooth sailing, though.
Crumbling to a straight-set defeat in Madrid against Argentine qualifier Maria Lourdes Carle, a week after pushing world number one Iga Swiatek on the Stuttgart clay, was a reality check.
Afterwards Raducanu complained about feeling "exhausted". It led to some criticism, including from her BJK Cup captain Anne Keothavong, but served as a reminder of the physical work still to do.
Managing her workload has been key, but it had a detrimental effect at times.
Raducanu played only once between the All England Club in early July - where she also pulled out of playing mixed doubles with Andy Murray in his Wimbledon farewell - and the US Open in late August, leading to a rusty first-round exit in New York.
Afterwards came a tearful admission that it was a "lesson learned".
Even so, Raducanu looked on course during the Asian hard-court swing to set a new personal high of Tour-level matches played in one year.
Missing the rest of the WTA season with sprained foot ligaments threatened that, but her BJK Cup appearances meant she equalled her previous best of 36 Tour-level matches.
After her BJK Cup experience, an enthused Raducanu immediately started her pre-season programme in London with a new addition to her team.
Renowned trainer Yutaka Nakamura, who previously worked with Maria Sharapova and Osaka, has been enlisted to help make her body more robust.
"I needed a more tailored approach and someone dedicated to me," said Raducanu, who travels to Brisbane this week to continue preparations before the new season starts on 30 December.
"My athleticism is a big strength that I have nowhere near fulfilled. I think I can become one of the best athletes in tennis."
Coach Nick Cavaday, her childhood mentor who she reunited with at the start of 2024, will continue his role as part of a tight-knit team.
Particular attention is being paid to turning her serve into a "weapon".
Lengthening her takeback, having gone to a shorter swing in the summer, has brought more rhythm, consistency and power.
"Yutuka adds another dimension to the way Nick and I work - it has become integrated and connected," Raducanu added.
"We can already see things that we do in the gym transferring onto the tennis court.
"We're on a journey of exploration."
