Maybe a tiny bit, but it was 5 days ago and it's not like athletes don't do hatd workouts 5 days before their A race.
No, what cost Femke the race was splitting the first 5 hurdles faster than SML and matching her at hurdle 7, in a race where SML ran 50.37. That is simply suicide for Femke, who always runs her best race by starting conservative and then turning on the jets in the last 100.
On her very best day I could see her finishing 0.5 behind SML for a ~50.87, that time loss would have to come early on - let's say the first 200m. Then from there she would utilise her engine to match SML over the second half of the race.
