It depends on the skater. Opportunities almost died around 2002 in terms of pro competitions and North American shows/tours. There was still COI and SOI but that didn't really force anyone to continue to push themselves.
Denise Biellmann was still competing 18+ years after her World Championship win with a triple Salchow and triple toe loop still in her arsenal, but that really wasn't common. Maria Butyrskaya turned pro after the 2002 season and then during the following pro competitive circuit, she struggled with her usually beautiful triple loop and triple toe. Again, I guess it all depends on how hard the skater wants to work once they don't have the pressures of amateur competition to deal with all the time.
