Kira Toussaint has again broken her Dutch record at 50 meters backstroke at the Rotterdam Qualification Meet (RQM) on Friday evening.
Among the men, Arno Kamminga dived well below his own national top time in the 200 meter breaststroke.
Toussaint touched in the final of the 50 meter backstroke in 27.37 seconds.
With that, the 26-year-old Amstelveen was twelve hundredths faster than in the morning, when she equaled her own record.
A few weeks ago, Toussaint improved the world record in the 50 meter backstroke on the short track.
Kamminga was a lot faster than in the morning with 2.06.85 in the 200 meter breaststroke.
Then the 25-year-old Katwijker already sharpened his own record with one hundredth to 2.07.17.
Kamminga already swam the Olympic limit at the end of last year and thus secured participation in the Games.
Earlier in the day, Tes Schouten beat Lia van Ee-Dekker's eleven-year-old Dutch record with 2.26.95 in the 200-meter breaststroke.
In the final, the nineteen-year-old South Holland remained just above that time with 2.27.18 and also fell short of the limit for next year's European Championship in Budapest.

De Waard beats Kromowidjojo
In the 100 meters butterfly stroke Ranomi Kromowidjojo was trumped by Maaike de Waard.
Kromowidjojo recorded 58.38 and was 0.28 seconds slower than De Waard.
Both swimmers met the limit for the European Championship, but remained above the limit for next year's Olympic Games in Tokyo.
Swimmers hope to obtain a ticket for the Games and the European Championship at the RQM in Rotterdam.
After this tournament, the maximum two fastest athletes per number will be nominated for the Games.
Open places can then be occupied by swimming a limit at the Swim Cup in Eindhoven (April) or the European Championship.
A number of Dutch top swimmers already swam one or more Olympic limits before it was even known that the Games were postponed to 2021.
Their tickets can only be jeopardized if there are Dutch people in Rotterdam who swim a faster time on the relevant numbers.
